I don't know about avocado plants. I have bought from them pawpaw tree, lemon tree, assorted bonsai trees, ground covers, a fountain, etc. And their service and knowledge is second to none. I have made avocado trees myself with the pits of eaten fruit. Since is pretty much an indoor plant, I wouldn't think so, but you never know.
I will text lorna and ask her and let you know. Lorna said no avacado plants sorry.
Maybe you can order them they have guava trees
