Bulk Discount Codes
Lilya: Bulk Discount Codes adds unique, single-use codes to Shopify discounts. A batch can hold up to 250,000 codes for a percentage, fixed amount, free shipping, or Buy X Get Y discount. Afterwards you see which codes were used, export them for your email tool or print them as QR coupons, and delete the codes nobody used.
The codes are ordinary Shopify discount codes. They keep working if you change plans or uninstall the app.
