this post. AmericaNet Bank and Evantage Bank both offer the same exact account, and all three also offer the same reward checking account. Refer to this post for reviews of these banks and accounts.
The fourth little known bank offering a 3% savings account is Danversbank. It's called the DBK Online Savings Account and it has no minimum balance requirements. I wrote a review of this account in this February 17th post. Several readers have commented on their experience opening this account. The bank is also still offering a 3.30% APY 4-month CD that can also be opened online.
For other nationwide savings accounts with 3-percent-plus savings accounts, please refer to my weekly rate summary. With the current financial environment, these rates may not last long so please check the banks' websites for the latest rates.
