Hi,
I'm looking for a reliable way to calculate UPS shipping given the box weight and dimensions. I'm working in ASP.net.
Does UPS have a web service or something you can use or do I need to buy some 3rd party software? I've seen a few of them for sale, but am not sure which ones are acurate/reliable.

thanks for the help!

Check out UPS's online rate tool: http://www.ups.com/e_comm_access/rates?loc=en_US

There seems to be an API here: ups.com (http://www.ups.com/content/us/en/resources/service/hardware/tools.html)
