Costco getting in the Unlocked Cell Phone Biz?

Just noticed an offering from a Costco email tonight, apparently they've started to sell unlocked Nokia smartphones. Clicking through the email link, the page pulled up four smartphones:
N97 ($599)
E75 ($419)
5800 ($299)
E63 ($229)
The deals are not bad but certainly not the best price we've seen.

Nokia Ups the Ante with iPhone-Fighting N97

Nokia said they would announce something exciting today and they sure did. How's a 48GB-touchscreen-slider-QWERTY-3.5G-5MegaPixel-Flash_support flagship phone sound like? If you like it, then you'll digg the new N97. This phone is so feature-rich but you'll also have to be rich to fork out the $700 asking price.
