It might be easier than you think to do your bit.
Bad news for Subway fans as their CEO, Trevor Haynes, revealed in USA Today that each franchise will get to decide themselves whether or not to keep the $5 foot-longer.
Launched back in 2004, the $5 deal has been incredibly popular, but franchises are worried that there is not enough profit margin to keep it up.
It’s not all doom and gloom.
While we might be saying goodbye to the $5 foot long, we could also be saying hello to some new fillings including a California Club, Pull Pork Crunch and Italian Grinder.
Haynes also hinted that Subway stores could be seeing some makeovers across the US and might even begin to introduce another American favourite to the menu in the form of burgers and paninis.
You win some you lose some, as they say.
