I've been working with someone selling plants on eBay who seems very reliable. S/he has answered numerous questions, usually within a couple of hours of my email. Of course I have no idea what the plants will look like, but they have a very good positive rating. One of the things I do when looking to buy something off eBay is to look at the sellers feedback score and then review the individual comments that have been left from buyers - if the seller / store has multiple types of items you can click on the actual auctions to see exactly which item(s) the buyers purchased.
I'll be planting my order at the end of next week - s/he is special ordering a few things for me. I'll leave info after I get the plants. If you want to know the name of the seller PM me - since I've not yet made the purchase I'm hesitant to put the name of the seller into this post as it might be taken as an endorsement (which I would only give after I see the plants).
