About K2 Digital
Section titled “About K2 Digital”K2 Digital builds websites, mobile apps, and ecommerce on Shopify and other platforms. Restrict Multi Discount Codes is one of our checkout apps for merchants who need to limit stacked promo codes or gift cards.
See our other apps on the Shopify App Store partner page, including HK Pickup, POS Cart Attributes, and AttrCart.
Does this app work on standard Shopify plans?
No. Restrict Multi Discount Codes requires Shopify Plus because it uses checkout UI extensions. See the App Store listing for compatibility details.
Can I limit discount codes and gift cards separately?
Yes. The app includes two checkout blocks. Set Maximum discount codes allowed on one block and Maximum gift cards allowed on the other. See Setup.
Why does checkout block when I apply two codes?
The default maximum is 1 for each extension. Increase the limit in checkout editor settings or remove extra codes. See Usage and Troubleshooting.
Can I ask about Shopify even if my question is not about this app?
Yes. Email tech@k2.digital on business days (HKT).
