Yea....you completely fabricated that entire post, other than the tax. Gas money? Unless you live in the backwoods or something, Walmart (they, in particular, have over 11,000 stores in the countries they're in) or some other store is within a few miles of you. Average fuel economy of a new car last year was 23mpg. Gas is $3.79/gal around me right now. Let's give you a 6 mile round trip. That's 26% of a gallon of gas. That's $0.98. So not a "few dollars". Yes, I just ran the math.
And any smart person would know not to go to Gamestop to trade in their games. You could buy a game new, $60, and they'd only give you $20 in return, even though they'd just turn around and sell it for $55. No, you go to mom & pop shops or eBay to sell your games. Uncharted 2, a 5 year old game (so it meets your criteria of games you know you're done with) still goes for $10 on ebay. So not "a dollar or two".
You only want, or at least pretending to want, to go all digital because Microsoft wanted to go all digital. Your topic is a stealth "Go Xbox" post disguised as a "we need to look ahead" post. Next time, open up the opacity tool and turn it down a little before you hit "submit"
