Unlimited Upsell review
Our top pick for BigCommerce upsell & cart drawer apps, out of the 4 we index.
Listing data checked 23 August 2026
Strengths and trade-offs
- 76 reviews, the most of any upsell app on BigCommerce
- Rules read off the cart contents, which is the offer type that actually converts
- 4.2 is a middling rating, and the complaints are about theme compatibility on custom storefronts
- Cart-based offers only — there is no post-purchase or checkout upsell
What "Free plan available" actually means
A free tier with usage or feature caps, and a paid upgrade above them. The most predictable model in this category: you can see the wall before you hit it, and the free tier is usually enough for a small store.
Whatever the label says, the calculation is the same: a upsell & cart drawer app has to lift revenue by more than it costs. Our break-even calculator works out the lift you would need against your own orders and margin — for most stores it is a fraction of a percent, which means the subscription is rarely the real question. The payload the app adds to every page load usually is.
