Hit the produce department at your local grocery store. Ask them to save you orange boxes (grapefruit and lemons too), and banana boxes. The citrus boxes are small enough to hold heavier items, like dishes, while the banana boxes are for the lighter items. They are very strong and stack well. I've moved twice using only those two types of boxes. Most stores will save them, if you ask. I have gotten better luck asking at the produce department rather than at the customer service desk. Lynn
