Which online seller do you trust the least?

[Psurfer]

I have to admit, I've got a couple of things from Buy.com that were faulty, one was a few dollar solar yard marker that worked literally for <30 seconds. And reading online, it turned out that a number of buyers had the same experience. (Their RMA return process seemed efficient enough, except I had already pitched the packaging, and altered the item, so no return for ME.)

So I get the impression they're not exactly vetting the merchandise very hard.
