The parents have a membership, maybe it's something worth looking at soon? There have been a few people mention Costco fruit trees on here.

I was surprised to see trees in bloom in 15 gallon containers for $29. Only saw basic cultivars. They may be full size vs. Semi Dwarf grafts so buyer beware.

I keep my existing full size trees all under 8 feet. All my trees are between 6-8 feet and are on full size root stock. I'm practicing backyard orchard culture where I can have more varieties of trees keeping them smaller through pruning techniques. There are growers in the Central Valley using this method as well planting more trees per acre and making harvesting easier, smaller equipment and better quality fruit. Check it our on youtube.

Down in Vista there is a guy doing that and I've seen pics there too. It looks great and is probably fun.
