I’m usually an Avis guy (recent problems notwithstanding). But sometimes the rates from other car companies are just too good.
I recently booked a colleague on a 13-day full size rental with Budget that came to $295 — that’s $22.69 a day including taxes and fees. Their United Airlines special offer gives miles and a real 10% – 15% off the best web rate.
Not always useful, but one for the arsenal.
