Manufacturers and retailers sometimes need you to ship your product back and forth for under-warranty repairs. And switching out a broken device for a new one under a store warranty is a heck of a lot easier with it's original packaging.
It's smart to keep those boxes around—if you have the space.
But whether you've got 400 square feet or 4,000 square feet, we could all use a little extra room. You need to remember to throw away those boxes as soon as your warranty expires. That's why we love this tip from Martha Stewart:
To store the receipt and warranty slips, place them in a cellophane bag. Write or type the expiration date on a self-adhesive label, and affix it to the bag. Attach the bag to the box with double-sided tape.
Now you don't have to go all Martha and buy cellophane bags. Any old envelope will work fine for keeping the receipt with the box. Or just jot down a "throw-away" date on the bottom of the box with a Sharpie marker as a note-to-self when you do your spring cleaning.
