Renting a car

Sheesh. The pricing methods on car rentals are even worse than airline
tickets. I always find this stuff facinating though – I wonder what are
the formulas behind this?

We’re going to rent a car for eight days when we visit my sister-in-law
(near Seattle) in a few weeks. I have two coupons for National car rental,
one for $15 off and one for 15% off.

I go to nationalcar.com and plug in all the info, first without any
coupon, to see what the regular rate is.

Then I go back and use the $15 coupon.

  • The rate I am quoted (before discounts) is $20 lower than without
    the coupon
  • I get the $15 discount
  • I get an additional $23 discount – no explanation

The rate is still over $100 so 15% should be better than $15, right? I go
back and use the 15% coupon.

  • The rate I am quoted (before discounts) is $50 higher than with the
    $15 coupon
  • I get the 15% discount
  • no other discount So it costs way more with the bigger “discount”

When I booked the next day with the $15 discount, it cost $4 more than it
did the previous day.
