C-store sales of both in-store items and fuels remained strong for the first three-quarters of the year, according to a survey of retailers released by the National Association of Convenience Stores last week.

Sixty-nine percent of c-store retailers say that in-store sales were higher than the same period in 2015. Only nine percent of retailers said that in-store sales were lower.

Strong c-store sales also pushed retailer optimism higher, with 73 percent saying they are optimistic about their business prospects in the fourth quarter, up from 68 percent last year.

Retailers also said that the holidays in the fourth quarter should help grow sales, as will the good weather and continued low oil prices, if they both continue.
