Of course freebies start showing up in the evening on the one day of the year where it's socially acceptable to start drinking at noon and watch sports all day!
If you have a free Kraft First Taste account, log in and click “my offers” on the left. A bunch of people (like me!) are seeing a coupon for a. If you're not already a member, you should sign up so that you qualify for their freebies in the future. Past freebies have included Oscar Meyar deli meats, Mac & Cheese, and DiGiorno pizzas.
Also, for people who have gotten a First Taste freebie in the past, you might want to check out the “Offer History” tab and take the survey for any freebie you've gotten. My gut tells me people who follow up on their freebies are more likely to be offered future ones.
