Cold Stone Creamery has reportedly inked a deal with Target Corp. to open four test stores inside the discounter’s stores starting this fall. Locations have not been determined.

The Arizona-based chain is venturing into new venues to boost sales. In March 2005, it opened inside Phoenix’ Airways Center to serve Phoenix Suns fans. In April, it began to indulge ice-cream lovers at Arizona Diamond-backs games.

The company also has started to expand into airports and amusement parks. It plans to open 25 non-traditional sites this year, including inside Phoenix Sky Harbor International Airport and at HersheyPark in Hershey, Pa. Other potential targets: resorts, universities and military bases.
