You realize that you'll never get new retail prices for anything once you taken it out of the store, right? You can get those 500GB units on ebay all day for $200 or under. Those games are worth $50 at most for the pair. And I'll give you $45 for the controller since people eat up those white ones for some dumb reason. Good luck getting anything more than $300 for what you're selling.
You also state $450 shipped but in the next sentence state that the buyer must cover shipping. Herp derp much?
