Some retail customers charged less for gas

The best gas savings are given out by Walmart and Kroger but you have to do some tricky things to keep from being over charged.  What some people are doing at Walmart is buying a Gift Card and getting 10 cents off per gallon of gas.  Kroger is doubling points until the end of the year so for every 100 points you earn you get 10 cents off per gallon.  There are no Walmart stores in the Alpharetta or Forsyth County Georgia area that sell gas.  Brendan Spaar is investigating the cheapest places to fill up his 2008 Infiniti.
