You have company. We get to our rented condo, unpack a bit, and head for Mega. Our shopping list would include cold cereal, milk, fruit, bread, sliced lunchmeat, chips, fruit bars, mayo, lettuce, tomatoes, eggs. and sodas. There's a bit more, but that's the bulk of it.
Coffee, fruit and cereal for breakfast. Picnic lunch that goes into wife's knapsack, and dinner out as she cooks every stinkin night at home. Usually one, maybe two "fancy" dinners out, and the rest of the time from carts, holes in the wall and their ilk, that we've discovered and traveled to via our hooves.
Thinking about it, I wouldn't call us cheap or frugal. It's what brings us the most pleasure.
