if you have a t-mobil plan, this may be your best bet if you are trying to get a new phone. otherwise, stay away from this store and do most of your work using the online store.
for one, the online store offers more discounts than this 'real' store - the only advantage is that you can pick up the phones you like so you can take a look at them. however, you can't work with the phones since they're all turned off and have stickers on top of them (very annoying).
the customer service is nothing to write home about - there's just one employee and if he's dealing with someone else, you're pretty much ignored.
