Thanks for that. I had seen the setting before on one of the other website I've built but didn't think of that 
I've now got everything working the way I want but for some reason the prices aren't showing in the emails that are sent to the customer and the shop owner.
As you can see the only time the price is displayed is for the grand total and not the unit price or the unit total. Is there another setting that I need to change or is there something I haven't configured yet? This is the 1st time I've seen Hikashop do this before. Any ideas whats going on?
