Discounts

Discounts applies offers automatically inside checkout — no codes to type, no stacking surprises. Rules are applied by a Shopify Function, so the discount a shopper sees is the discount they're charged.

Rule types

Every rule can be limited to specific products and scheduled with start/end dates. The rule's name doubles as the message shoppers see in cart and checkout.

Create and publish

Cartrella → Discounts → Create rule, pick the type, fill the numbers, Publish. Publishing registers one automatic discount on your store ("Cartrella Discounts") and compiles your live rules into it — unpublish or delete removes them just as cleanly.

Stacking

Rules use Shopify's native discount-combination classes, so product, order, and shipping discounts combine predictably — a quantity break and a free-shipping threshold can apply together; two order discounts won't double-apply (the better one wins).
