raintree nursery online is another mail order. local nurseries are better they will stock trees that suit the area and give you a better description the mail order descriptions are basicly worthless. for aditional information on rootstocks best suited to your area as well as resistance to desease problems in your area you can usually find state ag ed pages on the net now. I don't think most walmarts and homedepots or similar type retailers are very good at adapting to the locale and tend to sell the exact same product in every location. by the time you pay the shipping you will likely come out ahead to go to that local nursery.
