You will be prompted to enter your received discount code after you go through checkout and before you finalize the amount paid.
The discount will be applied to the original purchase amount excluding taxes and shipping unless already specified once receiving the discount code.
A percentage based and a specified amount based discount code will function in the same way.
If your amount specified discount code has a lower purchase value than your finalized purchase amount, you will be required to pay the remaining balance to complete your purchase.
Please feel free to contact us without hesitation at email@example.com if you have any questions or need assistance with using your discount code.
