EXPIRED possibly and some on other sites are reporting their reservation has been cancelled or that a "certificate" of some sort is required at the counter. If you booked under this code you should probably be sure to go with a back-up reservation as discussed earlier. The facts are unclear at this time so proceed with caution at least until renters this coming weekend can report back. Seems too good to be true but I was able to reserve with no credit card info. Hope someone here can use this "freebie" as well. AVIS "FREE" 2 day weekend car rental using code TUEA002 in most cities including Las Vegas for rental dates to 6/30/2013. You must pay tax/fees which amount to just $5.43 for my full size car at Bellagio. Airport tax/fees will be higher of course or if you book more than 2 days. Full pay rate would have been $164. Coupon Code: TUEA002 AVIS website is: http://www.avis.com/car-rental/avisHome/home.ac When you see the higher (regular) quote, click on it and the next screen shows the discounted price. Credit card was not required to confirm reservation.
