At some point this month, Jersey Mike’s is inviting you to have a great sandwich for a great cause…or two, or three, or as many as you like.

It’s the annual March Month of Giving Campaign at Jersey Mike’s, to benefit the Big Brothers Big Sisters Southern Lake Michigan Region.

All through the month of March, Jersey Mike’s customers will have the option to round up their purchase to the nearest dollar, or donate 1, 3 or 5 bucks to the cause when placing their orders.

The effort culminates on Wednesday March 26, when local Jersey Mike’s restaurants will donate 100% of the day’s sales — not just the donations — to Big Brothers Big Sisters Southern Lake Michigan.

The restaurants hope to break last year’s new fundraising total nationwide of $25 million. Jersey Mike’s has raised more than $113 million for local charities since the Month of Giving campaign began in 2011.
