I'm not sure Yellow. I seem to be on that random list myself. I received the F&F email last year and actually used the code but haven't received one this year. Not sure how it works. Been wondering that for years actually.
I was having problems getting Oakley promotional emails... A few months back, I decided to register a second email and then I started getting emails on both accounts. I ended up getting a code on my original email and not the new one. My last order from Oakley was back in March/April.
