Mine first, and to date, only eBay purchase was Metallica's Garage Days Re-Revisited CD. Garage Inc had already been out for a few years by then, so I already had the songs, but this was back in my rabid fanboy days, and it was one of those cool things that I really just HAD to have.
Cost me $45 bucks. Apart from a slight crease in the CD booklet, it was in pretty good condition. I think I bought it from some dude in Toronto.
