Xbox, just use "Create Profile" feature and make the profile. Once you created the profile, look for the ad. CLick the add and go to the "More Info" tab. Click and you'll see the 100 msp offer. Enter your REAL email once done change your GT (You'll have a free change) then submit your REAL email again and just keep on making accounts until you're basically bored or when their are no more codes left

it wont give me them again on my real email

Can I keep using same email though?

No you have to make a new account everytime you do it
