Found several branded S7 Edge cases @ AT&T Corporate Stores.(In Store only). Picked 3 for 12$ + taxes in Phoenix.
Buy Single case - 5$
3 or more cases - 4$ per case.
Several brands were there - Otterbox, Bodyguardz, Pelican,Case-Mate etc. It does not show up on-line. Go to store directly. Definitely worth, better than the unknown brand cases.
