What will be a competitive advantage of a traditional retail store?

The best I can think of is exceed service quality, product quality at a lower cost or retail pricing than the competitors. A plus is customer relationship and retention program.

hi,first of all its your advantage that your store location is at traditional market.becoz people sentimental attached with these type of markets and its easy to get the customer.For competing with modern store only one tool you required that is good service and friendly nature if once you win the heart of the customer then  that customer always feel comfortable to buy the goods from your shop,
best of luck for your business
