Goal: enable an upsell where customers can choose any product from an entire collection (e.g., 24 swimwear items) at checkout or post‑checkout, rather than showing only a few preselected items.
Clarification: functionality desired is similar to “One Click Upsell,” but with the upsell source being the whole collection, not a limited set of products.
Proposed solution: a vendor suggests using BOGOS.io to display a slider of discounted products from which shoppers can pick their preferred item. Setup involves defining the discount and then adding all desired products to the slider; screenshots were provided and are central to understanding the approach.
Limitation noted: another participant needs a “buy any 2 from the same collection” discount and reports most upsell/recommendation apps don’t allow configuring a Collection as the upsell source to display.
Status: no confirmed app solution that dynamically targets an entire collection at checkout/post‑checkout. BOGOS.io may work by manually including all products, but it’s unclear if it supports dynamic, collection‑level selection. The question remains open with no final resolution.
Hi everyone,
Is there an upsell app that allows you to click on entire collections instead of a few products?
I own a swimwear label, 24 pieces in my first collection. I would like the customer to be able to chose which product they want at a discounted rate at checkout/post checkout rather than me choosing for them.
Thank you!
Hello @sophiacalvi
Welcome to Shopify Community.
Do you have a reference of what you are looking for ?
Thanks
Thank you!
Just like the app one click upsell however I want to the customer to be able to choose the upsell product from my entire collection rather than me choosing 3 products for them at checkout
Hi @sophiacalvi ,
This is Ellie from BOGOS.io Free gift. What do you think about a slider that displays the products with discounted price, then the customers are eligible to choose their favorite one from it?
Here’s a screenshot for you. This can be created with the BOGOS.io app.
You can have all 24 discounted products appeared on the slider. To do this in BOGOS, you need to set your discount amount, then choosing all your discount products here 
Feel free to checkout the app! Hope it will help you store! 
Looking for the same thing and wondering if you found a solution?
We are running a promotion where buying any 2 products from the same collection will give the customer a discount. Every upsell and recommendation app I’ve looked into doesn’t have the ability to configure a Collection as the upsell products to be displayed.
