About Upsell Add‑Ons

Promote related products to your customer

Choose products to attach to other products as add-ons. You can promote products that customers might also want or need for a specific product.

Cart upsell

With the Ultimate plan, you can display add-ons the customer hasn't added yet on the cart page before the customer checks out.

Bundle products

You can automatically select add-ons by default on product pages. If you want to create product bundles, you can disallow add-on deselection.

100% mobile friendly

Works on every device, no matter what theme you're using.

Increase average order value

Show your customers products they might not know they wanted. It could be an accessory that looks great with an item of clothing. Or a gift wrapping service with a gift. The possibilities are endless in every industry.

Elegant and user friendly

No annoying popups or weird formatting on your site. Just an elegant, seamless integration with your store. Users can add how ever many add ons they want in a single "add to cart" click.

Unlimited products

There's no limits on anything. Add as many add ons to as many products as you want.

Easy for merchants

It's fast and easy to set up. There's no coding required, and it's simple to use while also being highly customizable. Choose specific variants that you want as add-ons for any product.

Hashtag Bamboo

I really tried to make this app work, in theory it should work great, but it keeps crashing and has caused a lot of grief in my shopping cart code. Don't waste your time like I did.

Love this app! It looks really nice on our product pages and the support is incredibly efficient and helpful!


Didn't work for me. Users had the option of selecting add ons but It didn't increase the price. So a product of $10 with a $5 selected add-on would still show as being $10.
