QRH2O review for Cart Lock:Block Checkout Rules
Feb. 10, 2026
This was exactly what I was looking for. A simple solution to block customers from placing unwanted orders. Very clean and no extra unwanted fluff. Strictly a cart lock just like the name. New update makes it easier to select specific products/variants to customize your needs. Very streamlined and customizable cart lock.
