❤️ Our Story

Family-owned, community-first

For more than three decades, our family has been proud to call Williamstown home, and prouder still to serve the neighbors who walk through our doors every day. What started as a small corner stop has grown into a South Jersey fixture, but the heart of it hasn’t changed one bit.

We know our regulars by name and their coffee order by heart. We’re the quick stop before work, the fill-up before a road trip, the late-night snack run, and the friendly face at the end of your street. That’s the small-town way, and we wouldn’t have it any other way.

With love, the family at Snack & Go at Sun Petro
