I have a number of products in my shop, most are standard (ie 20%) VAT, some are zero rated. I have set up the VAT rates, but whenever I change a non-tax price in the product, the linked tax price gets set to the same value. If I try changing the Taxed price the non-taxed price gets changed. The product is linked to the right VAT rate.
When I go to checkout, it calculates the VAT on the product and postage correctly, but only displays the non-taxed amount.
I'm guessing I've missed a fairly fundamental configuration step somewhere but I can't see it. What I need is for the product display (anywhere it's shown) to show the taxed amount - I'll settle for "£12.50 (£10.42 excl VAT)"
