Carts and Tools site sometimes offers many students discounts to save more study costs on a few occasions, so you need to check our site on some special events. If we offer a great discount at that time, you can utilize the coupons to save money.

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 Carts and Tools's policy, you can contact Carts and Tools via mail for your reference.
