Lowe's has a fabulous after Christmas clearance going on. If you need a new tree or other decorations, this is a great time to buy! Plus you can order online and pick up your order at your local store. If you do that, you don't pay shipping.
Remember though that not all items will be available at your store, but you can easily check online to see what is available.
Here are a few things I found. You can find more HERE.
