I take $50 a month because I work from home and honestly the things I most often get (Starbucks for example) I budget for. My husband does $50 a week - he uses this for random food he didn’t pack, coffee, papers, lotto tickets () taking his crew to lunch, random stupid tools & he stashes it for my gifts since I know what goes in an out of the account. This way if he wants to buy something he can and I can actually remain surprised
