Citibank is quite confusing.
They are still offering, through one link, an account called an e-Savings. This account must be linked with a Citibank e-Checking and, at present, offers a 4.75% APY.
They are also offering an account called the Ultimate Money Account which pays a higher rate, 5.00% APY, but comes with a lengthy stipulation:
