If you call their customer support, they will sound very helpful, but actually do very little. I had an issue with Stratosphere, the eBayer who sells Fender B-stock and less, now at improved A-stock prices!
Long story short, the imbecile sold me a 'new neck' which had clearly been detached for quite some time, with the truss cranked all the way. The neck was unplayable. I attacked it pretty hard to bring it in line - leveling frets, filing fall off onto the upper frets, etc. It was unplayable. But I had molested the thing, so it didn't seem fair to demand a refund.
We agreed to a resolution, which I thought was generous on my part. They would refund $50 in exchange for a positive review. eBay calls this "Ratings Extortion" and they will tell you it's a very serious offense which they will not tolerate. Except they so obviously do.
The reason I contacted eBay about this? After the generous deal I made with Straosphere, they will not sell to me or answer my emails (and it was quite a hunt to get to their contact info.
The "good news" is that after a couple months under string tension, the neck is now playable. It's not a very nice neck, and worth nowhere near my final cost, but it's playable. Too many ebay sellers, like Stratosphere are nothing short of scam artists.
