Budget has 3 insurance options:
LDW: Loss Damage Waiver. Basically covers their car if it's damaged/stolen. That's what the $64.50 appears to be.
SLI: Supplemental Liability Insurance. Basic liability insurance covering bodily injury/property damage
PAE: Personal Accident & Effects. For accident/injury/personal property.

Not sure what the $6.80 is, though.
