thats what i do.If you go to fatwallet.com you can see the seller ratings of most places and get some feedback. For newegg 7 pixel is not a lot but would annoy the shit out of me. Nothing beats being able to throw it in the car and return it.
You can also get a paypal debit card which works like a cc anyplace.
i bought my 52" sony from tigerdirect using paypal. it came with a free blueray player too.TigerDirect does as well.
