Holy cow!

A Louisiana supermarket was forced to yank its low-cost milk special after state auditors objected to the price.

Fresh Markets in Perkins Rowe was selling milk for $2.99 a gallon as part of a weekly promotion deal, but Louisiana requires that retailer markups be at least 6 percent above invoice and shipping costs, The Advocate reports.

State Agriculture and Forestry Commissioner Mike Strain said Fresh Market violated state regulations by selling milk below cost as part of a promotion.

The supermarket routinely sells a gallon of skim, 1 percent, 2 percent or whole milk for $2.99 on Tuesdays, limiting the quantity to four per customer, according to The Advocate.
