You can pre-pay for cellphone minutes, here in New England it's popular to lock in your heating oil price for the winter, and now you'll be able to bank gallons of gasoline on a debit card, thanks to MyGallons.com. While you're screwed out of the money if the price of fuel drops, it's not looking like that's going to happen soon. MyGallons uses your zip code to determine what price you'll pay to add gallons to your card, which is accepted just like a normal debit or credit card at most fuel stations. It's a creative way to smooth out the fluctuations in the price of fuel, and it could also be a boon to those wanting to run a tighter budget, or at least know what they'll be spending on fuel for a given time period, as they've pre-bought. Shoot, it could even be a decent gift idea for the person who has everything!
