yes they handle legal deals, full warranty. If they don't have in store, they will order with the best prices.
I'm actually going this weekend to find out how much they'll let a 9800 GTX go for, my friend is interested, and I can post. I think if you bring cash, they won't charge tax, if your a good customer, they give you more deals. lol They gave me 1 gig of ram for free, and they give me Arctic silver free, screws and sometimes extra stuff they have lying around.
Bring Cash, and bargain them. Ask for the price and try going down by 5 -20$. I kno that I got a 8600 GT for 38$ from them. I took it back because it was 85 degrees and horrible, got a 9600 GT OC for 160 Cash plus 30$ MIR so I basically spent 130 for the card.
and a couple other odds and ends. Whenever you go to one of those stores, they are always willing to help if you have $900 cash in your hands. And I was under the belief if they give you a deal for using cash, tax is pretty much **** and null, since it is obviously not going to be recorded anywhere.
