Save them! They are worth a fortune. I went to the UPS store to buy a 12 X 12 X 8 box and I wondered why she kept holding off on telling me the price. Well, the little box was $6.25. I thanked her and said that I could not afford that. I will begin collecting them where I can, spray them with cedar oil to prevent bugs from munching on them and cut the seams so I can store them flat. If you wonder why shipping on eBay seems expensive, consider the cost of the box alone. Amazon Prime is more and more of a bargain. Speaking of which, that has dropped from the national conversation.
