what do you mean by your first statement? if you're going to buy from amazon and it turns out they're going to charge you tax, most people in this thread seem to have been saying they'd seek an alternative...if your state doesn't have sales tax, NH for instance...then you can get it shipped to you from anywhere, amazon, best buy...wherever, and not pay sales tax. what i like about best buy is you get 4% rewards points, and 18 month financing. plus it supports a brick and mortar store where hourly people have jobs.
its true they dont have "everything", but they have a lot...it's a good alternative option for me, thats all.
