If you search for the best WooCommerce plugins for increasing average order value, you are not looking for a louder upsell. You are trying to run one of three jobs:
- Reward a larger basket with a quantity, cart, or BOGO rule the shopper can understand before checkout.
- Sell a set instead of a single item, with bundles or frequently bought together on the product page.
- Catch the moment after Add to Cart, or on checkout, with a shipping bar, a recommendation, or an order bump.
Those are different products. A discount-rules plugin, an official bundle extension, a checkout funnel builder, an upsell suite, a side cart, and a full store platform all answer the same Google query. They are not interchangeable.
This comparison covers six options people actually use in 2026, including WooDonkey. WooDonkey is not a $79/year plugin. Promotions, the add to cart popup, and bundles sit in one dashboard. That is a real advantage for some stores, and the wrong buy if you only need a quantity table or a checkout bump.
Quick comparison
| Tool | Price (1 site) | Best for |
|---|---|---|
| Discount Rules (Flycart) | Free, Pro from $85/year | Quantity, cart, and BOGO rules in wp-admin |
| WooCommerce Product Bundles | Yearly license on WooCommerce.com | Classic kits sold as one product |
| FunnelKit | Free limited, paid plans from about $99/year | Checkout bumps and one-click post-purchase upsells |
| UpsellWP | Free, Pro from $75/year | FBT, cart offers, and bumps without a full funnel builder |
| Modern Cart | Free, Pro for in-cart upsells | A side cart with a free shipping bar |
| WooDonkey | From $99/month, 14-day trial | Promotions, popup, and bundles in one dashboard |
Prices change. Check the vendor before you buy. Checkout funnels, shipping bars, and bundle types are covered under each tool below. The table is the job each option is built for, not a fake ranking from 1 to 6.
What actually raises AOV
A weak AOV plugin only adds another box on the product page. A useful one does four things:
- Gives the shopper a reason to add more that matches the product, not a random discount.
- Shows the offer at the right step: product page, after Add to Cart, cart, or checkout. Not all four at once.
- Keeps the math honest. Stacking three plugins on the same click looks greedy and breaks.
- Lets you turn it off without rebuilding the store.
If a tool cannot do the first two, skip it. If you need a custom checkout page and a one-click offer after payment, that is a funnel product, not a discount rule.
1. Discount Rules for WooCommerce (Flycart)
This is the plugin most stores mean when they search for WooCommerce discount rules. 100,000+ active installs. Free version on WordPress.org covers bulk, cart, and category rules that already raise AOV: buy 3, save 10 percent, spend $80 and get $10 off. Discount Rules Pro adds BOGO, role-based pricing, and scheduling. Pro starts around $85/year for one site.
Choose it if you live in wp-admin, you want a dedicated rule engine, and quantity or cart thresholds are the whole AOV plan.
Skip it if the problem is the moment after Add to Cart, or checkout, not the price list. A discount plugin will not show a shipping bar or a bundle picker.
2. WooCommerce Product Bundles
The official Product Bundles extension sells a kit as one product. Skincare routines, starter sets, accessory packs. Shoppers pick the set instead of adding items one by one, which is a cleaner AOV path than another coupon.
It is a yearly WooCommerce.com license. Check the current price. For Mix and Match, Composite Products, and cheaper bundle plugins, see the bundles comparison.
Choose it if you sell fixed kits, you want the Woo.com stack, and you are fine with one more first-party extension.
Skip it if you needed a quantity table on a single product, or a checkout bump. Bundles are merchandising, not a discount engine.
3. FunnelKit
FunnelKit (the Funnel Builder plugin on WordPress.org) is a checkout and post-purchase product. Custom checkout, order bumps next to the pay button, one-click upsells after the card is charged, downsells if they say no. That is a different AOV job from a product-page rule.
The free plugin is limited. Paid plans typically start around $99/year. Check FunnelKit for the current tier that includes bumps and one-click upsells. Setup is heavier than a discount plugin. You are replacing parts of checkout, not adding a coupon.
Choose it if abandoned checkout and post-purchase offers are the bottleneck, and you are willing to rebuild the checkout flow.
Skip it if you only needed “buy 2, save 10 percent” or a free shipping bar. FunnelKit is more checkout than merchandising, and it will overlap with other cart and checkout plugins.
4. UpsellWP
UpsellWP is Flycart’s upsell suite, listed on WordPress.org as Checkout Upsell and Order Bumps. Frequently bought together, cart offers, checkout bumps, thank-you offers, without FunnelKit’s full funnel builder. The free version already includes FBT and bumps. Pro starts around $75/year.
If you already run Discount Rules, this is the matching upsell plugin from the same vendor. That matters. Two Flycart products usually stack more cleanly than Flycart plus YITH plus a funnel builder.
Choose it if you want product-page FBT and a checkout bump, you do not want to rebuild checkout, and Flycart is already in the stack.
Skip it if you need a custom multi-step checkout and one-click post-purchase. That is FunnelKit. Also skip it if you already have a side cart and a popup fighting for the same click.
5. Modern Cart
Modern Cart is a side cart first. The free version already includes a free shipping progress bar, a coupon field, and Ajax cart updates. In-cart upsells sit in Pro. 50,000+ active installs. Built by the CartFlows / Astra team.
A shipping bar is one of the least aggressive AOV tactics that still works. The shopper sees they are $12 from free shipping and adds a second item. For other popup and side-cart options, see the add to cart popup comparison.
Choose it if you want to replace the cart page, you like Astra / CartFlows, and the AOV lever is the shipping threshold, not a new discount type.
Skip it if you already run a popup or a side cart. Two cart UIs on the same click will fight. Also skip it if the real gap is BOGO or bundles.
6. WooDonkey
WooDonkey’s promotions, add to cart popup, and bundles are native tools in one cloud dashboard. A small companion plugin stays on the store. Starter is $99/month for one store. That is more than any plugin in this list, on purpose. You do not buy WooDonkey to save $10 on Discount Rules Pro.
What raises AOV in the product:
- Promotions: product and category discounts, quantity tiers, Buy and Get, cart conditions, scheduling, coupons.
- Add to cart popup: confirmation on the same page, free shipping progress, recommendations from WooCommerce linked products, optional AI cross-sells you approve.
- Bundles: fixed kits and Mix and Match, with savings shown on the product page and in the cart.
It does not replace FunnelKit. There is no custom checkout funnel and no one-click offer after payment. Gift cards can lift a gifting order, but they are a different job. See the gift card plugin comparison if that is what you came for.
Guy Pappo at UNIQOOK: “I’m using WooDonkey’s Add-to-Cart, Bundles, Gift Cards, and Promotions, and I can’t recommend it enough. As someone who manages a super busy e-commerce store, it’s been super helpful, saving me tons of time and boosting my revenue.”
Choose WooDonkey if
- You were going to buy discount rules, plus a popup or shipping bar, plus bundles anyway.
- wp-admin is slow, or you manage more than one store.
- You want the AOV tools merchandised in one place, off wp-admin.
Do not choose WooDonkey if
- You only need quantity discounts. Use Discount Rules. The free version is enough for many stores.
- You specifically want checkout bumps and one-click post-purchase upsells. That is FunnelKit or UpsellWP.
- You already have a side cart you like. Stacking WooDonkey’s popup on the same click is worse than doing nothing. Test on staging and pick one UI.
How to pick in five minutes
Need buy-more-save-more and you live in wp-admin? Discount Rules.
Need kits sold as one product? WooCommerce Product Bundles, or the bundles roundup if you want Mix and Match too.
Need bumps on checkout and offers after payment? FunnelKit.
Need FBT and bumps without rebuilding checkout? UpsellWP.
Need a shipping bar in a cart drawer? Modern Cart.
Need promotions, the popup, and bundles in one dashboard, off wp-admin? WooDonkey.
If two of those sound true, do not install both on the same click. One AOV UI per moment.
FAQ
Will two AOV plugins conflict?
Often yes, if both open on Add to Cart or both rewrite checkout. Keep one overlay and one checkout. Discount rules can sit next to a popup. Two popups cannot.
Is a free shipping bar enough?
For many stores, yes. It is clearer than a random upsell. Modern Cart and WooDonkey both show progress after Add to Cart. A confirmation-only popup will not.
Do gift cards increase AOV?
Sometimes, when the shopper would have left without a gift path. They are not a substitute for quantity rules or bundles. Treat them as a separate product. See the gift card comparison.
Does WooDonkey replace FunnelKit?
No. WooDonkey does not build a custom checkout or a one-click post-purchase funnel. It replaces discount-rules, popup, and bundle plugins for stores that want those jobs in one app.
Is WooDonkey worth it only to raise AOV?
No. AOV is why many merchants notice the product. The plan is priced as a store OS. Start the 14-day trial if you also want catalog work, gift cards, or more than one of the tools above. If you only want a quantity table, use a free plugin.
The best WooCommerce plugin for increasing average order value is the one that matches the job. Quantity discounts are a solved, often free problem. One dashboard for promotions, the add-to-cart moment, and bundles is not. If that is what you came here for, look at Discount Rules plus Modern Cart, FunnelKit, UpsellWP, or WooDonkey, and ignore anything that only shouts “buy more” on every page.
Start a WooDonkey trial if you want promotions, the popup, and bundles in one dashboard. No credit card for 14 days.
