I wrote previously about Citibank Direct’s $50 promotion if you open an Ultimate Savings Account. They have just recently upped the ante to $100. The offer is only valid for first time Citibank deposit account customers. Here are some more details:

• 4.65% APY rate on the savings account
• No minimum balances
• No checking required
• Free transfers
• Only available online or over the phone
• To apply by phone, call 1-877-695-9400 and mention code: CYM
• Must be US citizen
• FDIC insured

While the rate is a bit lower than Washington Mutuals 5.0% Savings/Checking Combo, the bonus might justify opening a account with Citibank Direct.
