This is primarily what I use mine for. Sometimes i forget i put money there however, and a week later i look up and find a nice gift of $20 i thought I spent
I used to hide money in my coats in winter. I'd forget about it, then next winter I'd be a rich man. Or if I got desperate in the summer, I'd raid my coat closet. I used my overhead thingy once. My cell rang, and vibrated it's way out and scared me to death when it hit the console.
