The Motorola 2009 Retail Holiday Season Shopper Study reports that only a little more than half (51%) of consumers use their mobile phones for product information, comparison shopping and coupons. This number goes up to 64% for shoppers ages 18 to 34.
Another finding in the study is that at least 39% of consumers were willing to abandon a mobile purchase if they could not use or obtain coupons or discounts. A lack of coupons is considered to be one of the main reasons that an estimated 40% of shoppers abandoned carts altogether, double the 20% estimate from 2008. The report concluded that the majority of abandoned purchases could have been recovered if coupons and/or discounts had been readily available.
