Stop losing shoppers to the coupon hunt
When the discount field only exists at checkout, shoppers leave your store to search for codes — and many never come back. Put the field in the cart instead.

Frequently asked questions
Can shoppers stack multiple codes?
If your Shopify discount combination rules allow it, yes — CornerCart honors them exactly.
Do automatic discounts still work?
Yes. Automatic discounts apply alongside manually entered codes, following your combination settings.
What happens when a code is invalid?
The shopper sees an instant, styled error message in the cart — not a surprise at checkout.
