I just recently locked in a CD with virtualbank.com @ 5.50 % for a 3 month CD. While its only a short term CD it was the highest I had seen. If your in the market for a Money Market Account I would highly recommend them as well. This is what I ended up doing to get 20 bucks for FREE. You see virtualbank.com gives you 20 bucks for every referral that signs up under you.
I helped a friend who told me about there great rates. What you have to do is first get a referral from someone like myself. Next open a eMoney Market account. Its pretty similar to a savings account but pays way way better APR at the moment its 4.5% APR. After you open it with a minimal amount. Add a CD to your account and gain more APR. If you would like your FREE 20 bucks for opening email me at jefflmercer at Gmail dot com
