Amazon although the official wireless charger is bananas money so I'd suggest going elsewhere for that. Deffo going non-edge here, I get zero use out of the edge aspect of it but for those that do, it's a nice touch.
I had an S6 Edge and while the edge was amazing in terms of the screen and design I just didn't use it's features...now it's bigger it's become an easy decision for me to go with the S7 normally.
