I had this happen to me recently, there was a scratch card in the box and upon scratching it, I was told that I won $20 and to contact them. Then, when contacting them, they told me they'd send me the money but to please write a review on amazon. The thing is, I'd have written a 5 star review for that product otherwise since it is very good, but that feels a bit too iffy.
