Over the years I've purchased thousands of items on eBay. Much of it was supplies for my music students. In the last 18 months or so I've had numerous items that were mis-sized and I had to toss them out as it really wasn't worth the time to send them back. (I think that's what they're counting on when they mis-size items).
At one point, I closed my account and lost credit for all the purchases I had because I couldn't get things straightened out and I couldn't reach anyone at eBay to fix the problems.
Just recently, after opening a new account, I've had sellers for which I tried to post reviews but those reviews were deleted because eBay allows sellers to do that. So, I can no longer trust purchases from eBay as the rating system appears to be rigged.
