Consumers are clipping coupons at a rate not seen since before the 2007 recession, and that’s a troubling sign, according to Coupons.com CEO Steven Boal. The website tracks how often people view and print coupons and their redemption rate. Right now, Coupon.com’s Internet Coupon Index, as it’s called, shows a spike in coupon offers and demand. This pattern is almost identical to the one that played out right before the last major economic downturn. The higher the index value, the more consumers are under economic pressure, Boal told CNBC.com.
