Caribou Coffee: Free coffee on April 22 when you bring your own cup.

Earth Day is this Sunday, April 22, and Caribou Coffee is ready to celebrate. Get a free cup of coffee (up to 24 oz) when you bring your own cup, mug, tumbler, or other drinking vessel. Find a location near you.

There are usually some good Earth Day freebies every year, so let's see if we can find some more!

Free Flavor Friday! Get your free bottle of Coffeemate creamer.

Today is the long-awaited Free Flavor Friday! I've been saying that a lot this week, just because it's fun. The giveaway starts at 9 am PDT, which is just minutes away, so head on over and sign up for your free full-size bottle of Coffeemate creamer. Choose your favorite flavor!

They have 200,000 to give away, so don't panic if the website slows to a crawl, as they usually do with these big freebies.

Caribou Coffee: Free green whipped cream on Mar. 17.

Here's a slightly perplexing St. Patrick's Day freebie from Caribou Coffee. When you stop in on Saturday, Mar. 17, you can get free green whipped cream. It doesn't seem to require a purchase, but it also doesn't seem to include a drink. So... does this mean that if you order a drink that normally comes with whipped cream, you'll get green cream instead? Or that you can just walk in and request a free cupful of green, frothy whipped topping?

Well, if you live in Alabama, Colorado, District of Columbia, Georgia, Illinois, Indiana, Iowa, Kansas, Maryland, Michigan, Minnesota, Missouri, Nebraska, North Carolina, North Dakota, Ohio, Oklahoma, Pennsylvania, South Dakota, Virginia, or Wisconsin, maybe you can tell us.
