My post on facebook got randomly sponsored?

[Jeremy Greenwood]

So a few days ago there was a price mess up on amazon and there were LED torches going for a penny I ordered a hundred as a joke and made a Facebook post about it. Obviously my order was cancelled and they fixed the price but the weird thing is now my Facebook post is "sponsored", it's coming up in the ads section of my friends Facebook and I've had so many people ask and tell me about it, it's been there for days, why is this?
