Wow, thanks for that Facebook link to sync Amex with Costco - I have Amex Costco card and shop there regularly anyways, so $25 credit would be awesome! Not sure that I'd get the 14-person Thanksgiving meal, but thumbs up anyway just for the facebook info.
Just signed up for SD not 30 minutes ago, but already got 2 free PC game downloads, applied for a Barclay's home team Football MC with $400 statement credit, and essentially free $25 just for shopping at Costco... I LOVE YOU SLICKDEALS!!!
