Any good deals on Samsung Galaxy S7-S8?
eBay.
Hands down swappa.com , don't know how many of you have bought from them, but I have bought 6-7 s7 and 2-3 s8 all great condition some were even in the box closed, and the best part great prices, fees are half from what ebay and amzon charge so its the best place to buy from if your looking to get a decent phone for an excellent price, you can subscribe to a listing and wait till a decent price is posted or a color or what ever your looking for.
I recommend it very much, they have great cs, You can ask away from the seller and try haggling with him to lower the price when you know for sure you want to buy which is what I usually do.
Any questions feel free to ask me.
