Piggly Wiggly shoppers in South Carolina now can pick up a state parks passport — at a 20% discount — with their groceries.

Piggly Wiggly and the South Carolina Department of Parks, Recreation and Tourism unveiled the new partnership Wednesday (Dec. 5). The idea is to give customers another reason to shop at Piggly Wiggly while also getting more people to consider buying an annual park passport, Columbia’s The State reported.

“Piggly Wiggly has been ‘Local Since Forever,’ and the beautiful natural resources showcased and preserved in South Carolina’s State Parks have truly been around forever,” said David Schools, president and CEO of Piggly Wiggly Carolina Co. “The Pig family saw this partnership as a great opportunity to give our customers a significant admission discount to South Carolina State Parks.”

The discount, available in Piggly Wiggly stores in the Lowcountry and Midlands through Dec. 31, is 20%. That means the top level passport will drop from $99 to less than $80. That Park Passport Plus is good for all 47 state parks, and it covers admission for everyone in your family or in your vehicle. It also includes a copy of “Beautiful Places,” a coffee table book on the parks, and other perks.

Customers will get a voucher at the store that can be redeemed for a passport at any state park at any time in 2013. People who already have park passports can hold onto the vouchers and redeem them when their current passports expire.

Two other levels of passport are available at the discounted rate: The Statewide Passport, which covers all 47 parks, will be $60, and the Inland Park Passport, which includes only the 42 inland parks, is $40. Those are normally $75 and $50.
