The falling prices of gas is a welcome relief, but it's starting to feed an almost compulsive need to fill up my tank whenever I see cheaper gas prices.  Today I stopped for $2.28 gas, actually $2.48 for premium which I use.  Ended up getting 5.161 gallons for $12.85.  I know that I don't save that much money with the $.05-$.10 fluctuations, but I feel a sort of satisfaction knowing that I bought cheap gas.  It's the thrill of a bargain.  Unless of course, the gas is cheaper tomorrow.
