An aside: in Germany, “Hamstern” = stocking up on excessively large amounts of something that is feared to be in short supply thereafter, although it can carry negative connotation, as a selfish refusal to share with others (when I lived in Germany, I was always struck by people's general politeness and generosity, so hoarding for no reason would be frowned upon). Also, “Hamsterkäufe” refers to purchases made out of fear of a future shortage.
