Cart class discount

[eluser]BrainCatcher[/eluser]
Hi there,

I solved it msyself. I don't know of it's an proper solution but it works!

In the cart class i changed:

Code:

$items['price'] = trim(preg_replace('/([^0-9\.])/i', '', $items['price']));

to this:

Code:

$items['price'] = trim(preg_replace('/([^0-9\.\-])/i', '', $items['price']));

So the cart class is now accepting negative values as a discount.
