Subway fans have until Friday to win free subs for life, but the catch will require some legal fees

• Subway’s latest change will grant one fan free sandwiches for life.
• Hopefuls must legally change their name to Subway by Thursday night to enter the contest.
• The chain says it will also cover the legal and processing fees for the name change of the winning participant.

Subway is promising free sandwiches for life to one lucky fan, but they’ll have to make a pretty permanent change to qualify for the deal.

You have until Friday at midnight to legally change your first name to Subway if you want to score free sandwiches for life from the chain, according to a press release. Fans can visit SubwayNameChange.com to enter starting Tuesday.
