The commission of the foundation has not changes. It is in 2013 20% like it was in 2012 and 2011.

However, foundation must include VAT now, so real commission is now 20% (on price without tax) + VAT, so around 23.92% (and not 40%) on prices with taxes.

This is an example:

If you are a dolistore seller and set a selling price for a product to 10 euro without tax, selling price will be 11.9 euros (with the french VAT) for final customer, and you can claim 80% of the 10 so 8 euros without tax. You add your own tax to the foundation, so you ask back 8 + 19.6% of tax, so 9.56 euros.

So for a product sold 11.9 euro with tax, you get 9.56 with tax.
Or if you prefer, for a product sold 10 euro without tax, you get 8 euros without tax.
