One-click add-ons. Bigger carts.
Offer a relevant extra right under the main offer. Shoppers tick it to add it, no extra page and no code. The upsell rides along to checkout.
Upsells in three steps
Pick the add-on, price it, and it appears under the offer. Shoppers do the rest.
Pick the add-on
Choose the product you want to offer as an extra under the main offer.
Set its price
Give the upsell its own price or discount so the deal reads clear.
Shoppers tick it
One tap adds the extra. It rides along to checkout with the main product.
The right extra, at the right moment
A shopper who is already adding to cart is the easiest one to sell a companion to. Offer a matching add-on under the main offer and let them opt in with a tick, no extra clicks or pages.

Frequently asked questions
Browse the help centerWhat is a product page upsell?
It is a relevant extra offered right under the main offer. The shopper ticks it to add it to the order before checkout, without visiting another page.
How is an upsell different from a cross-sell bundle?
A cross-sell bundle groups products into one set. An upsell is a single opt-in add-on shown under the offer. Bundlex runs both from the same widget.
Can I show the upsell as a toggle instead of a checkbox?
Yes. Choose a checkbox row or a switch per offer, whichever fits your product page.
Does the add-on apply automatically at checkout?
Yes. Once ticked, the extra and its discount carry to checkout through Shopify's native discount engine, with no codes involved.
Do I need a developer to set this up?
No. Upsells are built in the Bundlex dashboard in a few clicks, and the widget installs as an app block with no theme edits.
How much does Bundlex cost?
Bundlex is currently free to install and use, with every feature included. For the latest plans and pricing, see the Bundlex pricing page.
