Please don't take my words, but ask UPS. I think $99 insurance is included in the shipping cost.
Depends on the shipping method, and I believe weight of the item as well. It is usually a relatively small amount, the only item I recall having a flat fixed amount is international express mail, which is insured for $100 (with option to add more at minimal cost).
Edit: I see it was shipped UPS not USPS - I think they have a higher included insurance, certainly worth a check, but a tough situation for the OP nonetheless.
