Some time ago the market gardeners from Villandry who have a stall at Loches market told me they had a vending machine in Villandry for selling their produce at the farm gate. Until the other day I had not spotted it, and it isn't really at the farm gate. Its location is considerably more prime -- it is in the Tourist Office carpark.
The veggie vending machine is a brilliant idea. Everything looked in good condition, and not outrageously expensive. I hope they do extremely well out of it.
Update: Here is a photo of the labels on the machine, showing the French distributor and the German manufacture's details.
