About Cart Lock:Block Checkout Rules
Cart Lock offers customizable conditions to block unwanted purchases based on specific rules such as country, product quantity, customer profiles, discounts, markets, and more—making it ideal for stopping bots. With real-time validation powered by Shopify Functions, it ensures only valid orders are placed. Transparency is maintained through clear warnings, keeping customers informed. Moreover it’s very easy to integrate, with a simple form, making it a straightforward solution for store owners. All charges are billed in USD. Recurring and usage-based charges are billed every 30 days. GREAT support when help is needed. I'd like to see one day blocking by last name but the customer tag or zip code blocking works for me. We appreciate the feedback! Glad the tag and zip code blocking works well for you, and thanks for the suggestion about last name blocking. Shahriar was very quick to help and got my issues resolved in a matter of minutes! Happy to hear Shahriar was able to jump in quickly and get everything sorted out within minutes. Great support.
