Tightwad Travel Tip – Splitting Expenses

David and I split grocery and transportation costs (gasoline, toll roads) equally. Rather than tediously figuring who owes what with each transaction, we draw from the zippered pouch we use as a kitty. Each of us contributes $20 (or 20 euros or whatever denomination we're using) to the pouch, and shared expenses are withdrawn from this fund which is replenished as needed.
