Do not buy any accessories at this store. Their markup is 600%.
As jaded as I am as a consumer, I was had at this AT&T brick and mortar cell phone store. My silly story will at least save you money.
Here it is: my phone was very old and I came in for a new one under the lure of the new $99 iphone ad online. Yeah, I love the new phone but the sales people at this shop are masters of manipulation. Lucas, who helped me was a fast-talking wizard at the sleight of hand techniques. He will likely graduate to selling used cars some day.
What to expect: all kinds of extra fees and add-ons plus hard sells on a warranty and accessories. DO NOT buy any accessories here. OK? Please, please do not. You can get the same stuff on the net for tons less. Example: I bought a "Silicrylic" skin for the phone. These jokers sell it for $30. Guess how much the manufacturer sells it for on their web site? $5. That's a 600% markup people. Don't fall for it. Same goes for car chargers,
