If your discount code isn't applying at checkout, first double-check that it's been entered exactly as shown, since codes are usually case-sensitive and don't allow extra spaces. It's also worth checking that your code hasn't expired and that your order meets any minimum spend or product requirements tied to the offer.
Only one discount code can typically be used per order, and discount codes usually can't be combined with gift cards. If you've checked all of this and the code still isn't working, contact our support team with the code and we'll help figure out what's going on.
