Hot dogs, American flags and fireworks are not the only items that see a surge in sales before Memorial Day, the Fourth of July and Labor Day. Mobile retail stores also see an increase in purchases during these summer holidays.

According to Internet Retailer, the retail search site Dealnews.com reported a rise in sales during Memorial Day, Fourth of July and Labor Day 2011. So far this year, the numbers have been steadily increasing leading up these holidays, and after Labor Day is over, the site expects the purchase amounts to be higher than last year. On Memorial Day, mobile traffic on the website – which searches for retail deals from online stores – reached 20.75 percent. This represents a 42 percent increase from the three working days leading up to the holiday. For the Fourth of July,  mobile traffic accounted for 22.48 percent, a 43 percent jump from the past three days.

Overall retail sales for July were better than expected, states MarketWatch. Industry experts anticipated that numbers would be dismal, as July is normally a slow month for retail sales. Retailers across the country are hoping that the positive totals will lead to a strong back-to-school shopping season.
