My GQ Code Isn't Working

❓ Why isn't my promo code working?

If you are receiving an error or the code isn't validating, please check the following:

  • Remove Dashes: Ensure you are not entering any dashes. The code must follow the format GQ123456.
  • Watch for Spaces: Make sure there are no accidental spaces before or after the code when you paste it.

❓ The code took me to checkout, but my total isn't $0. What do I do?

If the discount doesn't automatically apply at the final step, try manually typing your unique voucher code directly into the "Promo Code" or "Discount" box on the checkout page.

❓ Why am I being charged for shipping?

If free shipping does not automatically apply at checkout, please manually enter the code GQ BOX FREE SHIPPING (include the spaces) into the promo code box.

❓ What if none of these troubleshooting steps worked?
