LimitLock: Min & Max Limits

LimitLock is a Shopify App that allows ecommerce merchants to set and enforce minimum and maximum order limits at checkout, server-side. The app enables setting limits per product, variant, or collection, as well as order-wide item and subtotal limits. It ensures that the rules are applied on every purchase path, including accelerated checkouts, without requiring cart scripts. Shoppers are informed of the limits they hit and how to resolve them, with no need for theme edits and ensuring that checkout remains available even in case of misconfigured rules.
