I know I'm a FT'er and should be able to figure this out but for 9 bucks someone is selling the info. to get 50,000 for $500 and it doesn't look like a mileage run. Do you think it's the CC for 20k or so and then amenti for the rest? thoughts?

Here's the info from the auction:
EBAY Item number: 6597581950

Get 50,000 United MileagePlus Miles for only $500
Fly for free or in first class!
After winning the auction, I will send the bidder information from me in order to receive 50,000 United Airlines miles for no more than $500 into his or her United MileagePlus account. If you do not have one, you can create one right away. Please be aware that you are not bidding on the actual miles, but you are bidding on the information that will show you exactly how to get 50,000 miles for $500. You will receive the 50,000 miles for no more than US $500, and the process will involve NO fine print, NO meetings to attend, NO catches whatsoever. It only requires a few minutes of your time

This is a great way to get your miles! There are no catches. You pay $500, you get 50,000 miles! To buy only 25,000 miles on the United website costs over $600. This is a great deal!

I will send you the information through email and you will follow the simple instructions to receive your 50,000 miles for no more than $500. You will receive a refund if the process lapses. Therefore, you have nothing to lose.

Once the 50,000 miles are in your mileage plus account, you can then redeem them for valuable round-trip tickets! You can also use these miles on any of United’s partner airlines. 50,000 miles would get you two round trip domestic economy class tickets. It would even get you 5 one way first class upgrades, with miles left over!

Purchase with confidence and enjoy your travels! I welcome all questions!
