I'm going to have think of a tuna strategy post Brexit.
I was buying at least ten cans / jars in Cortes Ingles.
Plus olives, artichokes etc....
I once got a flight early back from Seville and sorted supper for three days in a suitcase.
You put up with it when you had the proper stuff.
Even the cans are superior in Spain. Last thing I do before I come home is fill the suitcase with Spanish tuna from the supermarket.
