Short Answer

You are up late watching TV one night and see an ad from Ronco for the Dial-o-matic food slicer.You learn that the Dial-o-matic sells for $29.95.But wait,there's more! Ronco is also including in this deal a set of Ginsu steak knives worth $10.95 and another free gift worth $7.95.Assuming that there is a competitive market for Ronco items,at what price must Ronco be selling this three item Dial-o-matic deal to insure the absence of an arbitrage opportunity and uphold the law of one price?
