Can we use multiple coupon codes

[cyberfolli]

I was wondering if there is anything out there that we can use multiple coupon codes at one time?

You'll need to shut the hard code functions off that only allows one discount coupon code to be calculated against the order total.

Hi - did anyone work out what the hard code functions were that needed to be shut off? I need to be able to put various % discounts on products in the same category for trade purchases and therefore require multiple coupon uses at checkout.
Any help would be appreciated.
