Oh my goodness, that's a fantastic tip! I've noticed the same pattern at my local store, but not with Market Basket. Our grocery store marks down their clearance on Wednesday mornings, right when they put out the new stock. I've learned to always check the clearance aisle first for baking supplies and canned goods. The key is showing up early before other folks get the good deals. It really pays off if you have the time to stop by regularly.
