free.gas

So over the past few months, whenever I donated platelets, I got a gift card for $25 to exxon/mobil. That's right...free gas. It was ideal. Since I was going in every two weeks, and drive my car fairly infrequently, I could have realistically gone for quite some time before ever having to pay for my own gas. It was good while it lasted, but unfortunately, all good things must eventually come to an end. Even though I tried to keep this saucy bit of info to myself, others must have found out, and now they've run out of cards. I must have totaled about 5 cards, and now I'm down to 1. In a couple of weeks I'll actually have to pay for my own gas again. It's unfortunate.
