I wouldn't waste my time trying to save/store them now. More likely than not they'll simply dry up; with no reserve energy in the corm they'll be unable to sprout next spring.

Glads are among the most inexpensive of the summer bloomers - available by the bag or box at the Big Box Stores, home improvement centers, Wal-mart, Sam's Club, Costco, etc. Buy some fresh ones in the spring and remember to plant them.

When I plant glads, and it's not every year, I always look for the packages marked "Grandifloras" - these have the big stalks and large florets. Because they're heavy and can flop, I plant them deeper and closer together than recommended. I dig them in the fall just to clear the garden space, but I don't try to save them. I know there are thrifty gardeners who find digging and saving the corms from year to year a worthwhile enterprize, but I never have.

Duluth, thank you for your advice and information on growing glads. I actually just had a look at the bulbs and they are pretty well dried out already. I don't remember what I paid for them, but I'll just have to chalk that up to experience. Something to look forward to next year.
