Yesterday I mentioned that flagship phones tend to drop in street price surprisingly quickly. Thank you, eBay sellers, for proving my point. Today the Galaxy S7 Duos, the dual-SIM version of Samsung's yearly upgrade, is just $529.99 on eBay for a new (not used or refurbished) phone. The prices for the Duos model aren't very consistent in dollars, but this unlocked GSM phone is almost $170 off the retail price of the single-SIM model at AT&T.

This particular version is model number G930FD, which means GSM-LTE bands (sorry, Verizon and Sprint users) and an Exynos processor. Also note that Samsung's dual-SIM design uses the second SIM slot as a combination MicroSD card slot, so it can't have two SIM cards and expanded storage at the same time. It's being sold as new, so it should have the standard Samsung warranty applicable. This is the bottom-rung 32GB model running Marshmallow.

Like most eBay sellers, this one is offering free economy shipping to the US. Other shipping locations (with varying extra charges) are as follows:

Canada, United Kingdom, Denmark, Romania, Slovakia, Bulgaria, Czech Republic, Finland, Hungary, Latvia, Lithuania, Malta, Estonia, Australia, Greece, Portugal, Cyprus, Slovenia, Japan, China, Sweden, Korea, South, Indonesia, Taiwan, South Africa, Thailand, Belgium, France, Hong Kong, Ireland, Netherlands, Poland, Spain, Italy, Germany, Austria, Russian Federation, Israel, Mexico, New Zealand, Singapore, Switzerland, Norway, United Arab Emirates, Qatar, Kuwait, Bahrain, Croatia, Republic of, Brazil, Costa Rica

A steep discount like this one means that the deal is not long for this world. Get an order in quickly if you want to take advantage of it.

The original listing now shows a higher price, but another seller just listed the same G930FD model for $529.99 here.
