box price

-- url of the page with the problem -- //http://www.herbashopoisterwijk.nl
-- HikaShop version -- : 2.2.2
-- Joomla version -- : 2.5.14

most of my products are individually priced, but there are a few how I need to price per box.
How can I change that?

Hi,
You can directly add it through you product description, or sell your product per box

I want to sell it per box, but the price of the product said per piece.
Can I change this?

You'll have to directly edit your translation file through "Hikashop->System->Configuration->'Languages'->YourLanguageFile".

I only want to change it for a few products.
When I do it like this I think it changes everywhere.
