No code works all the time in all markets...go down the entire list in the "sticky" until you find one that generates a good price.

Sometimes none of them do, or they require a component which I do not qualify for OR do not want. (like advance purchase) - but that is rare. Flexibility in where you can stay comes into play, too...but at least 80% of the time I am able to generate substantial savings by taking the time to check the codes.

The ones I listed were just examples....they worked for this trip, but at other times, nada.

It is also true that for some, the time spent isn't worth it - but it only takes me about 10 minutes to either find something, or to realize that I won't!
