Shoppers traveling to the U.S. from Mexico are having an impact on retail sales along the border.
Christmas shopping is in full swing and many shoppers have come from out of the country just to take advantage of some of the sales.
24-million visitors come to Arizona from Mexico annually, and they spend $976 million just in Pima County.
License plates from Sonora are a common sight at the shopping center parking lots across Tucson.
Their drivers spend long days shopping.
Roberto Valdez-Salazar drove ten hours from Navojoa, Sonora just to shop here in Tucson.
He just paid $20.18 for something he said would cost double in Sonora.
"There are always a lot of sales, the clothes are better quality, I always find my size and my money goes farther here," said Salazar.
He comes with friends and family at least five times a year.
