Footnotes plugin: a good one?


I wonder if anyone knows about a good footnotes plugin for WordPress.

I've found many, but non of them allows me to create a "reused" footnote.
For instance let's say that I have a list of prices and that I want to add a footnote with an asterisk (*) that tells readers the prices are VAT included.

Right now I would have to create a different note for each price, instead of a single note and an asterisk next to each price.

Anyone faced the same problem?
