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.

Checkout-only codes vs. in-cart codes

No feedback until the final step

How it looks

Codes validated where shoppers can still shop

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.
