Usually when people bring an appliance or a product home from the store, they rip open the carton and destroy any wrappings and other papers that came with the item.
It is wise to set up your product and make sure it is in working order before discarding the carton in case you have to return the item to the store.
Also, your item has more value if you ever decide to sell it on eBay or take it to a consignment shop. You can get much more money if the product is sold in its original container.
It is not a good idea to put boxes and containers outside in the trash where they can be seen by others. This is a sure way to let thieves know what big ticket items you have just bought. If you must discard your boxes, cartons or other containers, tear them apart and put out some of the pieces on different days.
If you decide to keep boxes, use them for storage containers. Pack winter clothes in them in the summer and summer clothes in them in the winter.
Think about these things the next time you are tempted to throw away that carton your new computer or printer came in.
