I received my first order from them yesterday and am really pleased. The plants are healthy and bigger than I expected after reading up on them. They inclued a two sided info sheet that had more information on it than some books I've read! I especially like that I can ship the packaging back to them for recycling and recieve a credit for future shipments. There was also a coupon book with many good deals. I highly recommend them!
