I drink too much Diet Coke, and thus have reached my limit in using their free iTunes codes (only 5 per person).
Thus, the following code can be utilised by anyone who wants it – first come, first get. Head over to iTunes’ site, find the ‘Coke Free Song’ section or whatever it’s called, and enter the following code to get a free song: TFFRNWCXSBMB.
If you try to use it and it doesn’t work, that probably means some-one beat you to it. Them’s the breaks, kid.
