The approach of Easter helped give a big 3.8 percent week-on-week lift to same-store sales. ICSC-Goldman's year-on-year rate also jumped, up 1.5 percentage points to plus 4.2 percent for the strongest rate so far this year. Easter, which falls of April 8 this year vs April 24 last year, always clouds retail readings but ICSC-Goldman is stressing that the strength it sees goes beyond calendar effects. Redbook, whose year-on-year rate has been trending one full percentage point above ICSC-Goldman for the last month, will be posted at 8:55 a.m. ET.
