This deal is too good to be true, especially you are an Amazon Prime member and a Prime car holder.
Sony Alpha A7 Mark II with 28-70mm kit lens is down to $998 in couple of sellers like Amazon and B&H Photo but the sweet deal from Amazon is that if you are an Amazon Prime card holder, you will get %15 back which brings the price of this kit to $848 (+tax). So for only $850, you are getting a great full frame mirrorless camera and a decent kit lens!
If you instead go for the latest A7, same deal applies for A7 mark III too, check here.
