I do not represent AAFES nor do I receive any benefit from them. As of 11/2017 all Honorably Discharged Veterans have access to the AAFES Exchange online stores. No sales tax and shipping is free for orders over $49 (or if you apply for and use a Military Star Card for your purchase). Their prices are usually less than other sites, especially when they have a sale, and they often have products that are sold out elsewhere (think 30 rd AR mags, toilet paper, masks, hand sanitizer, etc.). Worth a look.
