My only real complaint is they're not open year round. They are open while the seasonal fruits and vegetables they sell are fresh and in season which makes perfect sense. They also have lots of fruit spreads, marmalades, jellies, honeys, nuts, treats, juices, and more.
Friendly staff (I haven't run into the grumpy staff other people seem to have), good prices, and fresh product. I also haven't run into the spoilage at least one other person mentioned.
I haven't tried this, but I understand they ship products so you can share Arizona's bounty with friends and family out of state.
