Does the time or day when you shop matter? Apparently it does. You are more likely to get discounts on grocery items in the middle of the week because they restock on Mondays, Wednesdays or Fridays and at that time they'll mark down the prices of some items. To be honest I've never noticed such a huge difference or maybe it's because I wasn't being all that observant. Question: do you think people save more if they buy groceries in the middle of the week?
