Here’s an easy way to save when you buy produce that is pre-bagged and priced individually (not sold by the pound), like a head of lettuce, bags of onions or potatoes, carrots, etc.  Using the scale in the produce department, weigh several items and then compare these to see which one weighs the most for the same price! This works especially well with lettuce. You may get 20% to 50% more for the same amount of money!
