Last year there was a study done in Germany. The gas station prices change an average of 14 times a day. This really shocked me. I wonder if this is normal practice most other places.

It's 22 times a day, according to the Federal Cartel Office.

Here in western Australia, they must publish the price for the day by 2pm the day before, and cannot change it.

Definitely very different.
