how can stores like menard's give away products (after rebate)?
They always have something that is free or costs next to nothing after rebate. The rebate is in the form of merchandise credit. Who is losing money? The store or the manufacturer? Is it old stuff? I can't figure out how this works. Today in their ad they had tanning cream that cost negative $5.

how does our immune system produce the symptoms of flu?
What are the mechanisms and the immune response that cause symptoms such as weakness, muscle aches, sore throat, fatigue ? Bonus points for answering why producing these symptoms is beneficial in fighting the virus, but most importantly I'm wondering how it's done.

when something is government funded, how is the money transacted and who are the people who give and receive the money?

how are tabloid magazines that regularly publish false information about celebrities not get regularly sued for libel/slander?
Exactly what it says in the title. I was in a truck stop and saw an obviously photoshopped picture of Michelle Obama with a headline indicating that she had gained 95 pounds. The "article" has obviously been discredited. How is this still a thing?
