Expedia has a new tablet app, and they are having a flash sale today to celebrate. The sale offers $100 off your first hotel booking ($400 minimum) when using their app. Stays must be before December 31, 2014.

Here’s a link where you can enter your mobile phone number to get your individual savings code to apply to your booking.

The offer is intended for first-time users of the app, but I wrote previously that during a similar Expedia offer some readers were given the discount once the coupon was applied even though it wasn’t their first time using the app.

Here are the Terms & Conditions:

Offer: Receive an instant $100 tablet coupon discount off a hotel stay using the Expedia® hotels app on a tablet. The price of the qualifying booking must be at least $400 before taxes and fees.

How to redeem: Access the mobile app on your tablet and select a qualifying hotel stay. On the hotel billing and delivery page you will see a drop-down feature that states “Coupon Code”. click this feature and enter the code that was sent to you via text message.
