I have a new 6s+ and now my 6 128 gig I own b/c the 2 year was up (now I'm leasing). I was thinking of keeping it for a back up. Now for when the 7 comes out my wife's 2 year will be up and she will be leasing then we have another 6 128 gig that we will own. Should I get the 350 Verizon is offering while I can get top dollar for it now? What do you all think?
