HHGregg's five new stores in the Tampa Bay market open this week in advance of the hoopla of the official Oct. 15 grand opening. The fast-growing Indianapolis-based electronics retailer offers a 110 percent lowest-price guarantee, free delivery (through third-party contractors with reimbursement a rebate mailed on a gift card) and a commissioned sales force. "We compete on price and differentiate ourselves with service," said Dan Turner, vice president of Florida. The stores, which stock televisions, appliances, computers, mattresses and more, are at 13199 Cortez Blvd. in Spring Hill; 2669 Gulf-to-Bay Blvd. in the Clearwater Mall; 4495 14th St. W in Bradenton; 10277 E Adamo Drive in Brandon; and 6250 Commerce Palms Drive near the entrance to Tampa Palms.
