Should I raise my deductible after a 20% premium hike with a clean record?

[David.H]

I just received my renewal notice for my car insurance, and my premium has increased by over twenty percent despite having a clean driving record with no claims or tickets in the past five years. I drive a common sedan that's seven years old, so I'm really confused by the jump. For others who have shopped around recently, what's the best strategy for getting competitive quotes? Should I consider raising my deductible significantly, and are there any specific discounts I might be missing, like for low annual mileage or bundling with renters insurance, that could help offset this increase?
