How to find an upsell cart application for displaying promotions?

Shopify Apps

Topic summary

Seeking a Shopify upsell cart app that shows promotions and a progress/incentive bar directly in the cart. Goal: keep shoppers in-cart while adding eligible items and clearly tracking benefits.

Promotion logic: For each board purchased, customers can select up to $400 in free accessories. Merchant must manually set the suggested accessories per board and label the section (e.g., “To complete your kit”).

Required cart behavior: Suggested items must be addable from the cart; free accessories display at $0; a running “remaining to $400” amount updates in real time; a clear indicator confirms when $400 is reached. Preferably includes a shipping threshold bar.

Fallback offer: If no promotion applies, allow the same suggested products to be added as a bundle with a 5% discount.

Current pain point: Shoppers must leave the cart to find accessories, and discounts only appear after the $400 threshold is met. Merchant wants an app with a free trial.

Assets: Provided cart screenshots illustrating desired UI/flow are central to understanding requirements.

Status: Suggestions were received but didn’t meet the needs; no solution selected yet. Discussion remains open.

I’m looking for an Upsell cart application capable of displaying promotions and an incentive bar for adding products to qualify for the promotion directly within the cart.

My current promotion: For each purchase of a board, the customer can choose up to $400 worth of complimentary accessories.

I need to be able to program the suggested accessories for each type of board myself, and have them appear when the customer adds the board to their cart with a title below like “To complete your kit” (or similar), I want the suggested product directly in the cart, easy to cadd in the cart.

When the customer adds an accessory, it should appear at $0 and display the remaining amount needed to reach $400, and when the customer has added enough accessories to reach $400, it should clearly indicate this. Currently, the customer has to leave the cart to shop for accessories, which is complicated, and they only see the discounts once they’ve added enough products to get the $400 free (see my screenshots).

Ideally, in case of no sale, there should be an option to add the suggested products with a 5% discount (in a bundle).

I’m looking for an appropriate application that I can try for free. Also, if there’s a shipping bar available, that would be great.
