Free SkypeOUT for the rest of the year

I'm not an avid skype user, but I noticed that eBay / Skype are giving away free skype-to-us/canada landlines for the rest of the year. This is a really big promotion, but not THAT big. At first, it looks like they're making the product free, but they're really just trying to lure you in.

I still want to ditch my cox phone service and go with vonage. I just flat out want to pay less. I never use my landline anymore, and I just want something cheap for backup service.
