Retail sales slowed in the August 20 week according to ICSC-Goldman's same-store sales tally that fell 1.0 percent for a year-on-year rate of plus 3.0 percent which is the slowest rate in two months. Weakness at discount chains was a key feature of the week though the report notes that cooler temperatures helped back-to-school sales in the Midwest and East. Despite the week's decline, the report is sticking to its full month ex-gas call for a 3.0 to 4.0 percent year-on-year gain which would compare against ICSC-Goldman's gain of 3.5 percent in July and which points to little change for the government's ex-auto ex-gas category. Redbook, which has been trending higher than ICSC-Goldman, is up at 8:55 a.m. ET.
