I am such a pack rat and was saving packaging and boxes for just about everything. I've changed my ways (for the most part) and only save the packaging if I'm going to store the item in it or I need it for warranty work - some comapanies want it sent back in the original box. I was saving the acetate from packaging to use it to make window cards, but I have more than enough of that now. So now I recycle it all. Its just clutter that I don't want to deal with anymore.
That's my 2¢.
