Prevent checkout abuse by enforcing a single discount code. Keep margins healthy and checkout clean.
Stop stacked discounts before they hit your bottom line. One Discount Code Only (Checkout Guard) enforces a strict one-code policy at checkout, preventing customers from applying multiple discount codes in the same order. When more than one code is detected, the extension blocks the checkout flow and clearly prompts the shopper to proceed with a single code.
- One-code enforcement: Automatically blocks checkout when more than one code.
- Localize warning messages across multiple languages to match your store.
- Instantly validates discount inputs at checkout without theme changes.
