This offer is online booking only and available beginning at 12 noon eastern time every day through April 13. Rooms are available for the two days following each day of the sale. For example, today, Friday, April 2, reservations for Saturday, April 3 and Sunday, April 4 were available at the one cent price.
You have to be quick for this offer since there is only one room per hotel for the 350 properties in the Red Roof Inn brand.
I checked at noon eastern time today and found the San Francisco Airport Red Roof Inn available with a room rate of $0.01 for Sunday night April 4.
