For starters, why would you order anything from China? Even still, boots??
For obvious reasons, any company would have to run a credit card before shipment. Why the descrepancy of 92.99 and 101.13 could include a handling fee you were not aware of or could be an error that may be resolved.
It is very unlikely that UPS is the shipper, especially for a simple pair of boots. If it is a UPS tracking number, it would start with a "1Z' followed by sixteen other characters. The higher risk USPS is often confused with UPS, but is not a service available from China. China does have their own postal service that was probably used. It won't have any more tracking capability than USPS, so you'll just have to wait.
