I bought five 'brand new' Zippo lighters, lessee, over 15 years ago at a little country drugstore that was going out of business. They were all they had left, still on a cardboard display card, and no one could remember how long they had been there - but they had the original price sticker on them and were only $4.95 each. None of them worked, at first, until I removed the old flints, which had all been in there so long they just crumbled. Put new flints in, they all worked great. Gave four of them away, and still have the last one - and it still works.
