In case you enter a discount code during checkout that doesn't exist or isn't currently active, then you can see the message: “Unable to find a valid discount matching the code entered”.

Normally, one discount code is only applied for one offer. However, If the users put a vast of items in their cart, it is easy to use one coupon code to purchase items. It depends on YzGlasshardware's policy, you can contact YzGlasshardware via mail for your reference.
