I found these economy priced storage boxes perfect for moving my office stuff. The price was right too. They are as good as the more expensive Bankers Box.
If there is one thing you need for keeping clutter at bay is to get these easy to construct cardboard boxes. These are not the most durable and the price reflects that. However because of the easy way to get storage done and especially those that you eventually are going to donate this is a good cost effective way to use these boxes.
