The next time you spring for a Slurpee at a 7-Eleven, you could be buying it from a neighbor. The Dallas-based convenience store chain is looking to sell its Richmond-area company-owned stores to franchisees. It began the process here in 2007 but is making a bigger push now by reaching out to possible store owners. Of the 96 stores in the Richmond/Petersburg market, the chain has sold about 11 to franchisees. In the Philadelphia market, only two of its 155 area stores remain company-owned. In the Baltimore market, all but nine of the 175 stores have been sold to franchisees. Both markets have been pushing to sell their stores to franchisees for several years.
