Samsung US will continue accepting reservations for the gadgets that will be unveiled at the August 10 Galaxy Unpacked event for a few more days, the cut off is on August 9. You can make the reservation on Samsung.com or using the Samsung Shop App.
The offer has been restructured a bit – you can get $100 in Samsung Credit if you reserve just a Samsung Galaxy Z Flip4 or Z Fold4 or you can get $200 if you reserve a phone, plus a Galaxy Watch5 and Galaxy Buds2 Pro.
A note on how you can spend the credit: if you pick the option with just the phone, then the credit can only be applied to additional products, not the phone itself. If you don’t use it immediately, the credit will be valid until the end of October, so you will have time to mull it over. Another thing to keep in mind is that the credit can be used only once, ie you can’t split it between several smaller purchases.
If you get the three device bundle, you will be able to apply it to the same purchase. You only need to type in your email (and optionally your phone number) to make a reservation, there is no monetary deposit required.
You can find the full terms of the offer over on the Reservation page.
PS. There is a reservation deal in India as well.
