it changes on a daily basis. Yesterday price for gas at station by DL was 1.49 today it was 1.55. I was amazed at the 6 cents increase in one day. Sure it's the holiday weekend.
You can find it in about a .20 range in this area. Sometimes the stations right next to DL are among the cheapest, and sometimes they're more expensive. DH works at DL, so when we need gas he drives by all our usual stations for prices, then stops at the cheapest on the way home.
We live in an expensive area (always 15-30 cents more per gallon than closer to DL which is in a cheaper area)
