Lock It Up And Throw Away The Key

Right now a trend that’s beginning to pick up steam is locking in existing gas prices. Dot-com companies that allow you to buy your gas in bulk for a set market price are popping up all over the web. Through the use of debit-like cards, the company keeps track of how many gallons you purchase and applies that to your locked-in price for gas. Personally I think it’s an ingenious idea for the consumer–but if I was to sign up, I’d just like to know a little more about how it works on the back end. Do you think this price "lock in" has a future among the driving public, or is this just another fad to go with the times?
