Pro
Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureShow a cross-sell popup when customers add a product to their cart. Recommend related products and variants with a configurable discount (percentage or fixed amount). Choose which products trigger the popup and customize titles and button color. No coding required.
A free shipping bar tells a shopper they are $23 away, then leaves them to work out what costs $23. Cart Filler does that part: it offers two or three products that close the gap, and adds them in one tap. What matters is when it says nothing. If the gap is $3 and your cheapest item is $40, suggesting it means asking someone to spend $40 to save shipping.
- Show a cross-sell popup when customers add a product to their cart.
- Recommend related products or specific variants with discounts.
- Set percentage or fixed-amount discounts applied automatically.
- Only suggests products that actually close the gap - nothing outside that range
- Skips items already in the cart and checks every variant, not just the first
- No access scopes, and your storefront never contacts our servers
