The Original Recipe Slatherin’ Sauce, created by a Lowcountry native, is now available at Costco Charleston. The 32-ounce bottle retails for $7.99. Following a product test last year at Charleston’s Costco, it was determined the store had demand for the sauce. This year, similar tests will be conducted in Myrtle Beach and Wilmington, N.C., to determine if Slatherin’ Sauce will be sold in those locations.

Slatherin’ Sauce is also sold at many Charleston grocery stores and specialty shops in addition to shops nationwide, in Canada and in Europe. For a list of locations or to purchase online, visit http://SlatherItOn.com.
