Ditto on mint tins though they can be a bit small IMO. Ditto on ebay but by the time you consider the price of the tin (let alone shipping charges) you can usually find it cheaper locally (and get the candy to boot

) Wal-Mart can be a great resource if you know which departments to wander. Try Sporting goods at the beginning of fishing season, automotive, hardware, housewares, crafts, and electronics. I'm sure others have some suggestions as well. Let us know what you come up with.
*also trying to peek at the kit and its contents*
P.S. Leigh I am sure Susan will be VERY happy to know you consider her an honorary man (dripping with sarcasm).
