I have purchased from them many times, and have had most things live. They do guarantee what they sell, so if it doesn't live, you
should be able to get a replacement. I have never tried that, because even though I have had some things that did not live, it was entirely my own fault. When trees come bare-rooted, you need to get them planted as soon as you can, and do it properly. If you are rushed for time, and slap them in the ground and forget them, well, that doesn't work so well. Some smaller plants, you might want to pot up and get them growing for a year before putting them in their permanent location. As far as membership, the smallest rate is very reasonable, and they give you 10 free (very small) trees. Also, you can choose from several groups of free trees. I have had the free trees grow pretty well most of the time, even with my haphazard
gardening techniques. Last year, I had a little oak tree from them, and I planted it, and forgot about it for a while. When I went back to check on it, I could not find it, and figured it just had not made it. But this spring, there it was. It is about 8 inches tall this fall.
