Codes that are not working typically have been entered incorrectly. Check to see if there have been any spelling errors when attempting to make use of a code. Codes are case sensitive, as a result of this, copying and pasting is the most ideal way to use a code. This avoids such issues. Customers should also note that when attempting to use certain offers or discounts they may need to meet a spending threshold. Check out the terms and conditions if customers wish to learn more. They can also contact their customer service department.
