I am due for an upgrade on verizon and I was looking around for some promotions on iPhone 6 or 6 plus and wasn't able to find any. Is it okay to upgrade at BestBuy since they run promotional offers? I don't want to be charged extra for going through BestBuy than the actual verizon store. Also, is it worth it to even get the 6 at this point or should I just wait for the 7?
