Samsung's latest slate of Galaxy devices arrives on August 11, but there's still time to lock in a pre-order to get free perks like a storage upgrade and gift card. The company's new flagship foldable, the Galaxy Z Fold 5, is included in the offer. If you pre-order one, you can get double the storage (jumping from 256GB up to 512GB) and a $200 Amazon gift card at no extra cost.
