Saving on car rentals

If you are a Costco member, Costco Travel is a good place to start. You can search through major rental car companies and have coupons automatically applied.

You should book early, then a week (or a few days) before your trip, check the site again for lower prices. If you're flying at a slow season, prices might drop for last-minute travel. The savings are significant enough to take the time to do this (from $190+ to $150+ plus a class upgrade!). Don't forget to look at higher class levels. Sometimes, they are cheaper than classes below them (for example, a standard car might cost less than a midsize one).

Just don't forget to cancel your previous reservation, because a no-show or double-booking reservations is a jerk move.
