I've only purchased once through Tigerdirect, just recently. No complaints at all about the order or shipping. Friends of mine at work said they love Tigerdirect. I have not attempted the rebates yet. I hope I don't have that much trouble, but I know friends of mine who won't do rebates from anywhere because of the businesses pulling this kind of behavior.
Btw, why moved this to Buy/Sell/Trade? I would think this forum is just for us to personally trade with each other. No biggie, just asking.
