I've had a similar experience with small turkish shops in Vienna. The vegetables are cheaper, fresher, and there's more varity than in the major supermarket chains. I believe it comes down to centralisation. Major supermarkets only deal with large wholesalers than can deliver produce reliably to a large number of shops. A small shop on the other hand is happy to buy a single crate of whatever salad just happens to be available cheaply.
