Convenience stores are a $575 billion industry; however, since 2000 the overall sales, including gas and in-store purchases, have decreased. Most of that loss can be attributed to falling gasoline sales. While this sounds alarming, in-store purchases have actually soared, accounting for nearly 70% of all margin in the industry. Of those inside sales, the prepared foods category has been the leading factor in the increase of these sales gains. Of the top three producing in-store categories, prepared foods were responsible for over 28% of gross revenue.
