I've walked away from 2 large collections in recent months.
I cringe when I think of the dozens of great records I didn't get, and smile when I think of the 1,000s of crap records I didn't have to move multiple times before I carried it to Goodwill.
I've sold collectible toys, baseball cards and audio gear in eBay. I just sold my first record and I have to say that the bidders for vinyl are pretty picky and have so many damn questions. I think I dealt with more correspondence on one record than on my other sales combined.
I can't imagine all the time he will spend just fielding questions?
