Iconpack Makers - How much money have you made with your PAID icon packs?

Hey,

Thinking about starting to make a paid icon pack, have a few ideas and have the necessary skills to do it so why not.

In terms of money i would only charge £0.50 which i think is a fair price.

How much have you made from your icon packs? You don't have to be precise just a rough figure.

Thanks
