⚖️ 3. Negotiation & Savings Rules of Thumb

Coupons rarely stack: Most shops will not combine percent-off coupons with existing packaged specials or oil discounts.
Second quotes beat small discounts: A coupon saving under 10% of the total bill rarely beats getting an itemized second quote from an independent mechanic.
Confirm before booking: Always mention the coupon when dropping off your vehicle or approving the estimate, not at final checkout.
