Most mobile shoppers redeemed a coupon directly from their mobile device last year, according to a recent study from mobile shopping app Key Ring. Key Ring is part of G/O Digital, a Gannett Company.

The study found that 75 percent of mobile shoppers redeemed a coupon from their mobile device in 2013, up more than five percent year-over-year. The study also showed that 80 percent of shoppers said their perception of a retailer would change for the positive if the retailer offered mobile deals and coupons.

Consumers also reported that the biggest influence driving them to make a purchase is "an item being on sale." Nearly all shoppers (96 percent) surveyed said that they look at weekly sales circulars before shopping and more than half of mobile shoppers report that they would be more likely to look at the circular if they could access it on their phones.

The survey conducted by Key Ring examined more than 25,000 mobile shoppers.
