Ethics re: buying then returning stuff

[JustSomeJackass]

You can "rent" video games (movies/CD's) for free by buying it from the store...come home, play (watch) it as much as you want. Then take it back to a different store. Since all stores have a "no return" policy on this type of stuff...you take it back without the receipt, say you just got it as a gift, and it doesn't work (screen freezes, skips, whatever). They let you even exchange for the same title. Now you have an unopened product that you take back to the original store with the receipt...full refund granted. Just can't do it often at the same store
