I've always kept my machine boxes as you never know if you'll need it in the future. I keep mine up in the rafters in my front garage so its out of the house but close enough if I need it. I sold one of my embroidery machines as I decided to downsize after moving from Florida to Iowa. I wasn't using it much anyway. Had it since 2005 so having the original box came in handy. I didn't have to ship it as I made arrangements with the buyer to meet at an open area during one of my "road trips" to the "big city". Also sold one of my sergers and having its box came in handy as it was shipped and having all the stuffings inside kept it much safer while moving thru the mail service. I just feel better buying and/or selling a machine if it comes in its original box. That way I know its the original machine.
