I haven't but I'm a nobody on there. I doubt my word would mean much to a seller with a feedback score of over 6K
The problem is people like me get the seeds then leave feedback without seeing them bloom. This gives sellers 2-3 years to build up their feedback as a *good seller* and scam people the whole time. It's so sad too because it leaves a bad taste in the mouth of buyers on the LA. The same thing happened to many people who bought plant material on ebay. Now gardeners take that place as a joke.
