Things happen. Fulfillment mistakes that we make resulting in the shipment of incorrect product to you will also be accepted for return 30 days from the date of purchase. Generally, you will be asked to return the fulfillment mistake by First Class mail with a letter explaining the issue and we will exchange the product for you. We will typically send you a store coupon with the value of the return postage or a prepaid return envelope. We thank you in advance for helping us correct any fulfillment mistakes.
