WIth some shrewd use of discounts, I just filled my gas tank for 33 cents per gallon. I haven't seen gas that cheap since I took Driver's Education in high school. I told the gas station clerk this was probably his highest discount all day. He said it was second highest, and showed me a copy of a receipt for 1 cent gas (the maximum discount) filling a 20 gallon tank. Fill er up for 20 cents!
