When you buy new appliances, you probably never think of the warranty expiration dates. You happily throw the boxes away and then when something goes wrong, there is a problem. No box, no return. Here is a simple tip how to avoid this hassle.
If you put warranty expiration dates on appliance boxes, you will know when it's safe to throw them away.
Place the receipt and warranty slips in a cellophane bag. Use a marker to write the expiration date on a self-adhesive label, and stick it to the bag. Attach the bag to the box with double-sided tape. Done.
