I've linked to this before, but it's been 10 years and maybe you've forgotten. In any event, it's still an amusing site - with any number of charms, talismans, fetishes, juju's, what-have-you's to boost your luck and increase your mojo...

And their shop: http://www.luckymojo.com/catalogue.html
Without a doubt the most interesting shop on the entire WWW, Amazon, Ebay be damned...
