West Marine will commemorate the company’s 50th anniversary with a new promotion. On April 21, every West Marine location will give the first 50 customers through the door a mystery gift card valued from $5 to $100.

“All of us at West Marine are excited to celebrate out 50th spring season helping our customers get back to the boating activities they love,” said Doug Robinson, CEO of West Marine, in a statement. “We know that many of our customers are experiencing a longer than usual winter and are eager to spend time on the water. This event has been developed to serve as a great way to celebrate the start of the boating season.”

The total of the gift cards will reach nearly $120,000 and customers can go to www.westmarine.com/store-finder to find their closest location. Opening hours vary by store, the gift cards are available while supplies last and will be distributed on a first-come, first-serve basis.
