Shopping picked up sharply in the December 21 week, according to ICSC-Goldman whose same-store sales index rose 1.4 percent to a year-on-year 2.7 percent which is the best pace so far of the holidays. For data through December 22, shoppers finished 83.5 percent of their shopping, just about in line with 84.0 percent this time last year. In more good news for retailers, the report estimates that 31 percent of consumers plan to shop today on Christmas Eve.
