Free?

I think some companies don't really understand the meaning of the word "Free." The sixth definition in my American Heritage Dictionary, which I keep conveniently located on my coffee table (my Webster's is next to my bed), defines "free" as "costing nothing."

So, with this definition in mind, I thought it ironic that on the back of my cereal box, they were offering "free" keychains - at the cost of only two proofs of purchase and a $5 donation. Hmmm - two boxes of cereal cost approximately $5 each, so the total they are asking people to spend is around $15 to get this "free" keychain. Hmmm...maybe I should send them a dictionary.
