In regards to Ebay purchases anyways.
Awhile back I saw a nice framed print of a lady riding a bay horse sidesaddle. I thought "Oooh I want it!" but someone beat me to it. I saw it listed in January again and took the chance to snap it up. For $24.50, I figured why not. It was in a neat ornately raised frame.
I received it the other day and was a little disappointed upon unwrapping it. The frame is really gorgeous but the picture is ummm.... Well it looks nice from a distance. It's a pretty poor reproduction/enlargement and appears a bit pixilated and blurry. Not quite what I was expecting. Oh well, for what I paid, it's nice enough! The seller was really good to deal with and shipped it fast so I still left them good feedback.
The only other bad Ebay experience I've had was when a bridle I'd purchased arrived and upon trying it on my horse, the browband LEAKED dye onto my mare's forehead.... Not good.
