Product page does not display price with tax

The Products have a Tax Category (which is published) and they display correctly with tax in the Category Products listing level:
www.mymaninchampagne.com/categories-listing/category/12-e-books

However, in the main Product page, it is NOT showing tax. But when you add the item to the shopping cart it displays the price with tax:
www.mymaninchampagne.com/categories-list...-to-champagne-e-book

How can I get the Products page to display the Price with tax?

I would really appreciate some help.

Finally, worked this out! ( I tend to this after I post for help!)

For Products page to display prices with taxes, I need to go to:
System > Configuration > 'Main' tab > 'Taxes' section > 'Show taxed prices' has to set to 'Show tax'

Whereas, for the Category Products Listings to show prices with taxes I have to set it in the Content module itself:
Display > Content Module > relevant Content Module
