A retailer who purchases cigarettes and other tobacco products, fermented malt beverages, intoxicating liquor or wine directly from a manufacturer or producer shall compound the wholesaler markup with the retailer markup to determine the total markup on the merchandise.
Wis. Admin. Code Department of Agriculture, Trade and Consumer Protection ATCP 105.003
Section 100.30(2) (f), Stats., requires that markups be compounded when a retailer buys directly from the manufacturer or producer, thus acting both as a wholesaler and a retailer. In the absence of proof of a lesser cost of doing business, a wholesaler's markup is at least 3% and a retailer's markup is at least 6%, making the product's total compounded markup at least 9.18%.
