I need to hide UPS in the checkout whenever total order weight exceeds 800 pounds. (I already have customized shipping modules already in place for orders whose total weight exceeds 800, but are hidden when total weight < 800.)

So before I start hacking, I thought I'd ask if anyone else has already customized their UPS module in similar fashion. If it works with ZC 1.3.7 and the price isn't too steep, I would probably purchase the file modifications.

The url is ShedKitStore.com, for those who want to see what I'm talking about. It's a working store, so if you test the shipping methods, please include the word TEST in your name when setting up a customer account.

Thanks,
Sean
