First,i can not write a tax percentage with comma like 19,6 in France .How to to it?
Second The subject has been discussed, but nobody answered completely. How to do, if it does not take too much time working, for the price that i put in the product page in admin panel is tax free, (the script will calculate the price with tax) ,and the display on the page either with tax but indicating also the prices without taxes. On the order form ,obviously the price to pay is with taxes but also indicated the price without taxes.
