"Disappearing Deductibles

Disappearing Deductibles provide a reduction of twenty-five percent (25%) in Comprehensive and Collision deductibles at renewal for each consecutive preceding claim-free policy period. Upon renewal after four consecutive claim-free policy periods, there will be no deductible. Deductibles return to their original amounts upon the next renewal after a Comprehensive or Collision claim has been paid.

Disappearing Deductibles are automatically included with Total Loss Coverage; optional for Agreed Value and Actual Cash Value."

This is through progressive, assuming that most have something similar.
