I am looking at getting the wife a new tablet. BJ's has the following. 1. Samsung Galaxy Tab A 8" with a total of 64GB @ $110 2. Samsung Galaxy Tab A 10" with 32GB @ $160 3. Samsung Galaxy Tab A 10" with 128GB @ $230 All the tablets appear to have the same operating system and can have the GB's increased. Any opinions as to which is a better deal. Wife started out with the 8" but is now thinking 10"
