Ok so i bought microsoft points today. Quick few steps to get easy skins.

1) Must recover your account at your friends house.
2) Your friend must sign in
3) Download any skins that you wish
4) After you're finished re-recover your account on your xbox
5) Now go to Account Management under the Settings Tab of the Guide screen.
6) !@!@!@!@VERY IMPORTANT!@!@!@!@ You must do license transfer or else you won't have the skins.
7) After you do license transfer, you must redownload the skins from Download History under Account Management in the settings tab
8) Wala! Now you and your friend have the exact same skins for the price of 1!

**NOTE**
1) If you do this with the season pass, you will get the liquid metal skin, but you won't be able to download the DLC.
2) This method works with any DLC on the Marketplace, but you can only do License Transfer once every 6 months.
3) These skins stick to your account! If you switch skins you're able to switch them back! Unlike other methods.
