Changing Shipping Option
I build my cart using a flat rate for shipping. Sadly, this has cost me quite a bit. Well, I called UPS and they offered for me to use an API to get the total for shipping. How can I change shipping on my cart so that it no longer uses a flat rate, but will get the cost from UPS, without having to rebuild the entire cart again?
BTW, the cart was build using ColdFusion, so if I need to add any code, PhP won't work.
