Discover where did the offers go

I have Discover Cash Back credit card where you earn money per purchase. This credit card offered a good balance transfer plan to start the account with the first 12 months of interest free purchases. but now has lacked any good promotions to keep me using the card. I have made some large purchases on this card as the annual percentage rate is reasonable at 11.90% but not as good as my Chase Disney rewards card. I did sign up for a another balance transfer plan that was offered to me at a 3.9% financing and the fee was max of $75.00. I plan on keeping this card as a spare card and hope to see some better deals in the future come out of it so I can start making some purchases with it. I know if you dont use it over time they close your account so I will have to make some purchases on it to keep it active.
