The Samsung Galax S9 (GSM Unlocked) drops from $719.99 to $599.99 with free shipping at B&H. It will also come with a free AVODA TPU Case. This is the lowest price we found for an unlocked Galaxy S9 by $70 and you'll save an additional $20 on the price of the free case. This is the international version of the S9, so it will only work on AT&T and T-Mobile's LTE network. It will not work on Verizon, Sprint, or any NVMO carrier that uses those networks. There is no sales tax (except NJ and NY).
