I love eBay! That's not to say there aren't some jerks on there. I've had my share of not-so-great deals. But by far, the people are great and good deals are to be had. If I see misinformation in a listing, I usually send them a message and tell them. 9 times out of 10 they are grateful to be educated. Every once in a while you get someone who doesn't bother to update their listing...which usually means they KNOW they false advertising.
I saw someone once listing a common ol' 50s Indian blanket ($45) as a late 1800s Navajo blanket (for $350!). I wrote and told them what they had and they pulled the listing. They had me ID another blanket they had so they didn't make the same mistake. They had been ripped off at an auction but they got their money back from the auction house.
You can get good plant deals there including orchids.
