I'm sure everyone here already knew this except for me, but about two weeks ago I was browsing the rewards section and saw an offer for 250 USAirways Dividend Miles for Free, so I redeemed $0.00 of my e-rewards and got 250 miles (they've already posted), then my husband logged into his e-rewards account and did the same thing.

Now today I logged in and was browsing the rewards section and found 500 Club Carlson Gold Points for Free, so went ahead and redeemed $0.00 of my e-rewards money to get myself 500 CC gold points, then did the same for my husband.

Anyone know how often the switch up the free travel points rewards?
