If you don’t want to wait for the Yun Shield, you can go online to radio shack, they have the Arduino Yun for only $39.97. This is a better deal than the $51.97 I paid a few months ago at local RS that was closing.

No wonder, Radio Shack is bankrupt and sold in a lot of pieces. What remains of the few shops that are still open and carry the name/logo, just isn't "your father's Radio Shack" anymore. It's just another cell phone shop, nothing related to DIY electronics by a long shot...
