Can't you just use a shipping band to do free shipping? That's how all of my clients do it.
You set up shipping bands like
Up to $40 charge $9.99 flat rate
Up to $1000000 charge 0.00 flat rate
So if the subtotal is great than $40 they get free shipping?
Just curious as to why you'd want to mod the cart for something it can do by standard unless (in which case excuse me please!) that I've completely missed the point of this mod above
