Seven ways to cut your Naperville premium

Re-quote every renewal. Insurers price new business below renewal business. Staying put is the most common reason a premium drifts up.
Raise the deductible to $1,000. Takes roughly 9% off the comprehensive and collision portion — worth it if you can absorb the excess.
Bundle home or renters. Multi-policy discounts of 10–20% are standard, and renters insurance is cheap enough to pay for itself.
Drop collision on an old car. Once the vehicle is worth less than about ten times the annual collision premium, the cover stops making arithmetic sense.
Ask about low-mileage and telematics. Under 7,500 miles a year is worth roughly 6% on our model, and usage-based programmes can beat that.
Pay in full. Monthly instalment fees add 3–8% over the term.
Fix the credit-based insurance score where Illinois permits its use — it moves premiums more than most drivers expect.
