Pacific Service Credit Union is offering a 3.50% APY 6-month certificate for new members. Maximum deposit is $1,500 per member.
This used to be a much better deal back in 2007 when the maximum deposit was $5K. Now it's only $1,500. So you'll only make about $15 more than what you would make if you had the $1,500 in a 1.50% savings account. Thus, I didn't feel it was worthy of a blog post.
Also note that the required savings account has a $100 minimum to avoid monthly fees.
For more details about membership, refer to my 2007 review.
