I bought my parents one of these as a gift, but I had both tablets (actually six total, due to making two accidental orders which they apparently were unable to cancel) ship to me. So how do I make sure that my parents will be able to use the $25 credit, oh and the $10 wallet credit too? I wasn't planning to open their box before mailing it to them. Will they be able to set it up using their gmail address and receive the playstore credit? Also, I was thinking of selling the add'l 4 tablets on eBay/CL but if a new owner can't utilize the credits, I will probably refuse shipment. TIA.
