I'm always looking for new ideas to add to my bankroll. Here are my current methods: - IF I come back with cash from the last trip I spend half (usually on jewelry) and put half away for the next trip - Cash in credit card points - I have a very trusted friend at work. Once I book a trip I give her all the money left in my wallet at the end of the week. Sometimes I cannot believe how much that can add up, considering I don't use cash for much anymore. - I never spend dollar bills. I keep those stashed away for CW tips. If I accumulate more than I need I change them in for bigger bills for my bankroll.
