Coupled with the rising costs of rent, labor, and food, the increased local competition made the $5 footlong untenable for many franchisees. Around 2012, Subway quietly phased out the promotion, and footlong subs returned to a $6 price point.

In March 2008, Subway began offering the Five Dollar Footlongs as a short-term promotion to end in May, but since it was so successful, Subway made it a permanent staple of its value menu in one form or another. The advertising campaign for Subway's Five Dollar Footlongs wasn't luck, but sheer campy genius.

What happened to Subway's $5 footlong deal? Blame inflation. Subway's $5 footlong sandwich promotion, which was introduced during the dawn of a recession, could not withstand rising costs, and naturally, the price had to go up. Per Forbes, cumulative inflation rose about 14.3 percent between 2007 and 2015.

The $5 Footlong is officially back thanks to fans just like you who have been asking for its return.

You may recall the lawsuit against Subway Restaurants for selling “12 inch” and “footlong” sandwiches that were allegedly less than 12 inches long. The case attracted lots of media attention and consumer sniggers because of Subway's ubiquity (and the endless possibilities for double entendres).

Subway was accused of selling footlongs that were less than 12 inches but the case was thrown out.

An investigation launched in 2014 after a woman notified police that Taylor had offered to send her images of child pornography. In July 2015, Fogle's Indiana home was searched by state and federal authorities. Taylor and Fogle were arrested.

In a win for class action fairness, the saga of the too-short Subway sandwich lawsuit has come to an apparent end after plaintiffs abandoned efforts to pursue the case further.

azodicarbonamide Remember Subway's “yoga mat chemical” controversy? In 2014, a petition created by blogger/activist Vani Hari, AKA Foodbabe, urged the chain to remove azodicarbonamide, a substance also found in yoga mats, from its bread. Just days - and quite a bit of public backlash - later Subway agreed to phase out the ingredient.

If eating a footlong sub is more food than what your body is used to eating in one sitting, you may feel bloated, nauseous, and even heartburn due to overeating. For some people, eating something that is the size of a literal foot can be way too much for their tummy to handle.
