Carriers aren't looking to cut you a deal. Installment plans are just contracts by another name. Last year's phone is not "just as good" as this year's.
These are the three golden rules of Black Friday smartphone shopping. There are other important things to consider, sure, but those are the fundamentals that everyone needs to know and abide, because if you don't, you could end up with a phone you don't want that's stuck on a carrier you don't want to be with. And that sucks.
