Cheaper rental cars
Rental car prices swing wildly — the trick isn't finding the cheapest quote once, it's re-shopping it until pickup day. Book refundable early, then let automation do the rest.
AutoSlash
VisitThe deal: Free reservation tracking: hand it your refundable booking and it rebooks you automatically when the price drops.
Use it well: Book the earliest refundable rate you can find, then submit the confirmation to AutoSlash's tracker and forget about it until the alert emails arrive.
Watch out: Some agencies blocked AutoSlash's initial search display — today it's best used as a tracker for reservations made elsewhere.
Costco Travel
VisitThe deal: Consistently among the lowest member rates, with free cancellation and a free additional driver.
Use it well: Compare against your AutoSlash-tracked price — take whichever is lower at each re-check before the trip.
Watch out: Requires a Costco membership; inventory can sell out on peak weekends.

Read the storyHow to stack it
- Always book the pay-later refundable rate first — never prepay a rental car.
- Pay with a card carrying primary rental collision coverage (Ritz-Carlton, Venture X, Sapphire Reserve) and decline the counter insurance.
- Check Costco, AAA, and airline-partner discount codes before the first booking, not after.
