<prompt> Human: The savings game So Ive done something similar for years, Ive never seen anyone else do something like it! I take out my grocery shopping money for the week or month from the ATM all 20s when I shop, anything I get as change, under a 10, gets thrown into a jar. At the end of each month, I count it up, roll the coins, etc. then it gets deposited and I keep track of the amounts! It usually ends up a couple grand. I put it in a vacation fund It also helps limit my spending on unnecessary things.If you havent tried something like this, I would definitely recommend it!For non-cash users, I hear a lot of banks will do a similar thing, of rounding up transactions to the next dollar and keep the change in a separate account for you!  <response>: Ive done this before as an experiment when i switched to a small money clip fits my ID, credit card, debit card, and at most three bills and I ended up with about 800 in 6 months, though I also set everything below a 20 aside and had my coins converted. When I ended the saving game and used my credit card exclusively I see on average about 15 to 20 in cash back per month which I redeem in 25 increments that gets deposited into my checking account. In the end any rewards card is better than just stashing away money you already had. If you want it to feel like something youve put aside you can just let your rewards balance ride and collect a big chunk later.
