When I filled-up up at Costco near the office last night I paid $3.759 for regular, 9 cents less than last week at the same place. This morning I filled my wife's car at the Costco near our house and paid $3.799, which is about the normal spread.
Most of the name brand stations around are now under $4 so there has been some relief from what was, at least locally, a high of around $4.359.
