Chain-store sales surged in the June 28 week in ICSC-Goldman's same-store sales sample, up 1.0 percent compared to the prior week for the best year-on-year rate, at plus 4.6 percent, since December 2011. This is the second straight very strong showing for this report. With the exception of grocery stores, ICSC-Goldman reports strength across all retail categories. Redbook, which has been showing less strength, will be posted later this morning at 8:55 a.m. ET.
