The McDonald's Deluxe line was a series of sandwiches introduced in the early to mid 1990s and marketed by McDonald's with the intent of capturing the adult fast food consumer market, presented as a more sophisticated burger for adult tastes.[1] The sandwiches sold poorly and the entire line was discontinued on August 18, 2000. The Deluxe series was a marketing disaster and is now considered to be one of the most expensive flops in McDonald's history.[2][3]
