L2 offer code?

I am trying to register L2. I notice that this time it says I can enter “offer code” in my shopping cart. I suppose the “offer code” will give me discount. Under what circumstances will I get an “offer code”?

CFA Charterholders do have a discount when registering for level 2. Just kidding. The cell was there in the software package that CFAI bought - but they don’t use it (i.e. there is no “offer code” available)

Thanks for your reply. I think I can take my time to register now
