Right now, they are 'selling' for a premium on eBay, even though most of these sellers don't even have the codes. Once the codes are actually on the market, the prices will drop. I estimate that the 'common' pre-orders will be in the $15 to $20 range. Consider the eBay/PayPal fees and my MSP is not all that much lower. Obviously, the rare ones (Best Buy did terrible marketing) will be harder to get, which is why I am already offering 1600 MSP for that one. I may offer more, once we see how the market pans out. Just FYI, I was able to get all but the Wallmart codes for Fallout at 800 MSP each, so it would seem that some people just don't want to deal with eBay or the gray market.
Also, just as a side note, eBay does NOT cover the transaction in the event that there are any problems. Please refer to the eBay ToS regarding the purchase/sale of digital content. The seller can simply claim the 'code' didn't work, and eBay/PayPal will AUTOMATICALLY refund their money. Period. The seller is SOL. I know this first hand after selling some Chocobo and Reach Beta codes (and getting scammed out of hundreds of $$$ -- Chocobos were like gold for some incomprehensible reason).
EDIT: also will gladly work with a
"middle man" for the transaction in the event that anyone is skeptical about my codes being legit.
