Ebay is a very dangerous place to shop. It is full of thieves & idiots, so buyer beware. Some of the sellers don't know what they are selling and some are just crooks (there are some good, reputable ones as well). Pictures they post often do not match the description so it leaves you wondering which are they sending you -- what they show you or what they say it is?
I bought seeds for grains of paradise (Aframomum melegueta). Fortunately, I had gotten some Aframomum seeds from Soren so I knew what to expect for appearance. After a number of notes back & forth, I was able to determine that I got Afrocarpus seeds. Going through a similar thing right now, trying to determine if the seller is selling cardamom, black cardamom, or sharpleaf galangal (fortunately, I have not ordered yet).
