I went to Costco for tortillas and tortilla chips and ended up loading trees into my car. They had a huge selection of bare-root fruit trees for $10.79 each, great bargain in my book. The trees are about 5-6' tall and come in with roots loosely bagged with a bit of soil. They are all grafted onto semi-dwarf and seem well suited for my region. I ended up with a pear and cherry tree, too bad they didn't have the apples I wanted.
They also have the combination trees with 3-4 different pears or apples if that is what you were looking for. I ended up selecting species that work well in my area and are self-fertile.
One thing about Costco, if they have what you want buy it as it will likely be gone next trip.
