How to score cheap gas at Kroger

If you buy groceries at Kroger, you are probably using the fuel points. Getting extra points requires some planning and watching Kroger's ads - -

When Kroger offer 4X fuel points,

1. Buy gift cards to restaurants, such as O'Charley's, Cracker Barrel, Texas Roadhouse, etc. Use these for eating out.
2. Buy gift cards for birthday gifts, Christmas gifts, etc.

Complete the cash register receipt survey for 50 extra points.
