SCOTTSDALE, Ariz. -- Convenience stores may be rebounding from an unprecedented first-half of the year, if late second- and third-quarter figures are to be believed, according to one research firm. Trip frequency is up slightly in the second and third quarters for c-stores after declines in the first quarter, according to Kurt Orr, vice president of consulting and innovation with the Chicago-based Information Resources Inc. (IRI), who spoke exclusively to retailers at the CSP Consumer Insights Forum in Scottsdale, Ariz., earlier this week.
