There is one on Gran Canaria, saves 70% compared to the toursist supermarkets
Don't know if they are good for personal. In Holland there where problems for years with the union that the cashier had to stand behind the register and not allowed to sit. Also they had to remember all the codes cause a scanner was to expensive. Don't know of that is still the case. The owners are rich cause they don't spent.
And the quality is good overall. But for chocalate they use for instance second class cacao. But made by Droste Chocolate.
