I personally would never order anything online from Gamestop, Best Buy, etc.
Probably only Amazon and Ebay. And maybe a few random sites.
Yeah I got a monitor from Best Buy and it came broke. I happened to know the manager at one of the Best Buys near here and he replaced it for the sale price. Otherwise I would have had to pay another $50.
Newegg >>>>
And yeah I like eBay.
