An instance of twisted logic

So i was gonna keep the Shawscope set, but then it's late, if not here by the 17th i can get a refund, meaning to make it like i did keep it with the equal amount spent on kindles since yesterday, i can now get 160 dollars more of kindles, because it was established the other day that i could keep the set, this way i can have 2 sets worth of kindles with no set.
