Amsterdam seeds was the very first place I ordered from, and they did come through; only problem, so did homeland security. They took the contents of my package, placed tape with homeland security in red letters on the package, and sent it on.
It's just me, but that's one reason I prefer Canadian businesses; it just seems like traffic from Europe is watched more closely, but that's just my opinion.
I just had a successful transaction with Rhino, but after the initial confirmation e-mail, communication was non-existent, and it took well over a month to get the order; not knocking them, but just stating facts. They did finally come through.
