I had a link to the ad from their site, but it won't take you to the ad when you click on it, it just refreshed the CAG page. Wierd. Anyways, just go to CC.com and at the top right on the red background, there is a link to the weekly ads.
Wierd again. Searching the site, if you go directy to Socom 2, it's $19.99. But if you search the weekly ads online (or offline as I did), it shows as $9.99. If you click the link from the online ad to buy it, it still show's up as $19.99 when you go up to the Socom 2 page. Just call customer service and you'll be fine. They advertise that price, so they have to give it to you.
