Irwin Union Bank has an eye-catching summer promotion on 11-month certificates of deposit.

Customers can earn from 1.90% to 2.21% APY, depending on where they live. (Users enter their ZIP code to see the rate for their area.)

Those returns are considerably higher than the national average of 1.15% APY and approach the 2.30% being paid by the best 12-month CDs available nationally.

Then, Irwin Union throws in a 22-inch Sharp or LG flat-screen LCD HDTV. They cost about $300 at online shopping sites such as Amazon.com. (You also have the option of a FLIP camcorder from Pure Digital Technologies Inc.)

The minimum investment to qualify for a TV is $20,000. It's sent to your home 30 days after the account is opened, with Irwin paying the UPS charge.

There is a steep early-withdrawal penalty: 91 days worth of interest plus $500 deducted from your principal to pay for the television.

Irwin Union has 30 branches in nine states -- Arizona, California, Kentucky, Michigan, Missouri, Nevada, New Mexico Ohio and Utah -- but this offer is available nationwide, and accounts can be opened online.

Here's where to compare the quote you get from Irwin with the best CD rates from dozens of other banks in our extensive database.
