We ran out in the bulk tank last week. Best price I have seen for diesel is 4.09. I pait 4.14 today. I am going to take the small bulk tank we use on job sites and fill it up at the 4.09 and put it in the big bulk tank when i go by there. I called to get the big tank filled and delivered was going to be 4.30. it has already effected our pricing.
