My family has sent stuff like these back to Readers' Digest for years and we have never won anything from them. They keep offering stuff at inflated prices ($88 for a book?) and not very well-made costume jewelry unevenly studded with Swarovski crystals which you have to buy to be eligible for certain additional bonuses (a car this year).
My mom had already crushed the stuff and was going to toss this in the waste paper basket but I thought perhaps we could just send it in one last time since I could use a car and extra cash when I get married. Might just be a silly thing to do, but oh well.
