If you are selling played cards, I think the scale tips slightly in favor of eBay (make sure to take pictures and list clearly), followed by TCG, with buylisting bringing up the rear simply because most buylist make heavy deductions for played cards (ranging from $0.70 to $0.30 cents on the dollar)

Slight wear to up to two corners upon magnification, a couple of very slight chips to the edges, or a couple of very small scratches or printers marks are acceptable with an 8
It is useful when you can drip feed dorks in you were saccing off anyway and milk a bonus damage out of doing so
You can't play an 8 drop in a normal deck and have much chance of it doing anything
