Additional shipping options, shown on your website, are available ONLY w/ UPS. I did not know that, checked USPS and could go no farther.

It'd be helpful if "UPS" were stated somewhere near that info. VitalChek was unable to help; she said the "only" options were USPS or UPS.

Once I'd gone back and checked "UPS" instead, I found a small drop down box on a later page that gave me the $17.50 and 19.50 options.
