I don't post every internet freebie or deal I see around because many of them are flooded on other sites and some aren't all that great of a deal. Here's a couple that seem to be pretty good and are one-day only deals.
My Coke Rewards has a one-year subscription to Cooking Light magazine for just 150 points TODAY ONLY! This is a great magazine and I believe you can also get the digital subscription free with the print subscription if I remember correctly!
Kroger's daily Cart Buster deal of the day is BOGO Chef Boyardee can or cup. You can only load this to your card today and it expires 10/31/12.
