Description of stocking-stuffer idea:
Great for a variety of situations. If you have an active teen who often needs to eat on the fly, then fast-food gift certificates are great. If you know someone's favorite store, but have no idea what to get them, allow them to get what they want. You can also get money vouchers at gas stations for fuel, tokens for car-washes, etc!
