Auchan Hypermarket's two-hour special sale at its Changyang branch in Yangpu District on Tuesday night resulted in crowds and chaos.

At least one shopper fainted and children were left crying in the crush as crowds stormed the shop at 10pm trying to find the discounted specials. "I was shopping about 9:30pm and was astonished to find people rushing to the store late at night," said a customer surnamed Cheng.
