I was looking online as I always do to see if I'm do for an upgrade. To my surprise I was and on top of that I see that At&t is selling refurbished IPhone 4's for $99!!!! I was so excited I couldn't believe it. So I rush to add it as my upgrade hoping that they haven't sold them all out and at the end when I'm about to complete my order for my phone I see that my total comes out to $174! ($99 + $17 activation + $57 taxes). What's up with that??? Given I understand that I live in CA and sales tax is ridiculously hight but to pay $57 in taxes on a phone that's $99. So at that point I did a little research and found out that only 3 states charge taxes on that full price of a phone prior to the discount and of course CA is one of them. So I figured since I'm heading to Colorado on vacation in a few weeks, should I just buy a brand new IPhone at Wal-Mart (which is $147) or should I get a refurbished now???
