Retailer Bull Moose, which sells new and used music, movies, video games and books, said it plans to open a store in South Portland this fall, marking its 11th location.

The store will be located in the former Blockbuster location in South Portland’s Mill Creek neighborhood. Bull Moose plans to expand the building by about 50 percent to 11,000 square feet. The renovations will create 60-75 construction jobs, and the store will have 15 permanent retail jobs once it opens in the fall, the company said.

Green Crossing Blue, a sister company of Bull Moose, bought the former Blockbuster store for $1.12 million in March, according to city tax records.

Bull Moose had tried to open in South Portland last year at the former Border’s Books & Music location at the Maine Mall, but the store was bought by Books-A-Million.

Bull Moose was started in 1989 in Brunswick by Bowdoin College student Brett Wickard. The company now has more than 100 employees. Bull Moose operates eight stores in Maine and two in New Hampshire.
