You may encounter an error stating "The gift certificate or coupon code is invalid" when attempting to utilize a coupon code during the checkout process.

This situation may arise due to various reasons, including:

  • Being an international buyer
  • Not meeting the minimum purchase requirement (the minimum amount for the first order discount is $150)
  • Already having received a further discount on the transaction (e.g., through a free shipping offer or quantity discount)
  • Having items on sale in the cart that cannot be discounted further
  • Trying to discount an item restricted by federal or state funding regulations
  • Including items in the cart category that do not allow additional discounts
  • Having already applied a discount to a previous transaction associated with your email address.

Regrettably, this error code cannot offer more detailed information. Nevertheless, we trust that this explanation sheds light on some of the underlying issues.
