I can't find any code for Galaxy tab E purchased Wal mart.com and picked up at a Walmart store. Walmart.com said "A confirmation of purchase email is sent first, within 48 hours expect a second email from the distributor containing the activation or redemption code;" however, I haven't received any Email from anywhere besides Walmart.com receipt which didn't show any code.
