@matigo Ha. I'm just gamifying it whilst I'm here: since so many things get charged sales tax, the game is how little money I can hand over to the government. (Fresh groceries in general don't get taxed though, by my understanding, and buying second hand often works reasonably well for other things.)
As for meat, unfortunately I think the shelves just aren't full enough for things to expire. The meat aisles in Aldi or Lidl are hardly crammed.
