It's (sort-of) back! Book a 2-night stay on Orbitz, use promo code VISACHECKOUT on a promo code eligible hotel, and pay using the VISA Checkout system, and get $100USD off. It's a "while supplies last" promo, so hurry.

You will pay the taxes on the full $100 AFAIK.

From the last deal, it doesn't look like you actually need to use a VISA card with the VISA Checkout system.
