UPS SurePost is a hybrid service that uses the U.S. Post Office for last-mile delivery of the package. This economical service is available, though, only if UPS has added it to your UPS account.

If you want Boxify to include UPS SurePost (in addition to the regular UPS rates it obtains from UPS), check the checkbox marked, "Display SurePost rates" on the screen you use to configure UPS. (Click on the button marked,"Configure UPS" on the Boxify dashboard.)
