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 Costway's policy, you can contact Costway via mail for your reference.

In case you need to change another Costway Coupon Code, or you no longer want to use the item, you can cancel your Coupon Code by a press on the Cancel tool at Costway. We will support you if you have any trouble via our mail.

It depends! Normally, the percentage that you can save with that Costway Coupon will be shown right on the page, so you can see if it is applied sitewide or not. However, once you are not sure, try it right on their's products you want to buy.

The sitewide discount from Costway is applied on certain purchases. For Year-End Deals, the store may have its own requirement to offer you a sitewide discount.
