Who Knew? If you hate crowds when shopping for your groceries, apparently Wednesdays, after 9 pm is the least busy time of the week to shop for groceries. According to Progressive Grocer, just 11% of shoppers go to the store on a Wednesday, and only 4% go after 9 pm! Well, I don’t know about you, but 9 pm is too late for me, however, I am certainly going to shop more often on a Wednesday!
