The American Express Spending & Saving Tracker survey found that price discounts are the top motivator for consumer spending this holiday season. The online survey, which queried a random sample of 2,011 consumers ages 18 and older, reveals that 70% of consumers say discounts would get them to shop within the next 30 days. On average, a 30% discount was enough to get them to spend. Nearly half of consumers (45%) said free or faster shipping would encourage them to shop. Other perks also are attracting shoppers, including a free gift with a purchase (35%) and bonus reward points (22%). Echo Research conducted the survey between Oct. 29 and Nov. 2.
