Thanks, all!
Exit - my experience with Home Depot spanned almost exactly one year. I figure that if they don't come through on their promises before I buy the carpet, then I shouldn't have expectations that they'll do that after I give them my money. If they weren't going to send me samples,then they shouldn't tell me that they were going to. They brought up the idea of having samples sent to my house, not me. I certainly do appreciate the info, though. I still buy things from them, but likely will not buy flooring there. Also, their prices were just about the same as Carpet One once padding and installation are included, so it's kind of a wash for me.
One thing about Carpet One that seems too good to be true (so I'll read the fine print), but that is very interesting, is that they have a 120-day satisfaction guarantee. Apparently, if I don't like my flooring within 120 days, they will come out and replace it for free. I'm assuming that I would have to get the replacement carpet from them, but still - that's a nice service.
