lol.. my chocy bars don't last 5 minutes..
but it's not the chocolate that's important..it's the wrappers..
for collectors and film studios, it wont take them too long to make up some form of block that will sit inside the wrapper to fill it out.
And it's not just choccy wrappers, but cereal boxes, vegetable packets, electrical goods boxes etc.
Almost anything that displays a product form yesteryear is of value to someone in advertising, film, TV, or collections and museums.
Personally, I think it's quite an interesting 'antique collectors' hobby in comparison to old worm ridden furniture that stinks of moth balls
