Important notes for auto-apply coupons

1. Auto-apply feature will trigger only when there’s something in the cart
2. Smart Coupons will check the validity and all the restrictions and limits set for the coupons before auto-applying them. For example – If you restrict a coupon to “Customer” user role and “Stripe” payment gateway, the plugin will first verify whether these restrictions are met and then apply the coupon.
3. Up to five coupons can be auto-applied by default even if you’ve enabled the ‘Auto apply?’ option in more coupons.
4. Your users can remove any auto-applied coupon if they wish to. But if you want to change this behavior and you can also don’t allow your customer to remove auto-applied coupons.
5. You can bulk generate coupons with the auto-apply feature.
6. Auto-apply feature works with subscription coupons as well.
7. Auto-apply feature is not applicable for gift cards/store credits. That means users can’t auto-apply gift cards/store credits.
8. Auto-apply will not be enabled for coupons that are linked to a product. That means when you issue any coupon with a product purchase, that coupon will need to be manually applied by the users on their next purchase.
