It's a hobby, and hobbies cost money. I do most of the grocery shopping in our house and seem to be in the store several times a week. Use the debit card to pay, get cash back (a 20), now and then, and it adds up. Squirrel it away in a safe place until the stash becomes enough to play, and viola. That, and side jobs, or when some reimbursement check or something else comes in, deposit all of it but 20 to 50 and keep the cash. The key is not to make big ATM withdrawals.
