New to ACCADiscount code for Kaplan too, or just BPP?

I'm new to ACCA and have been very fortunate to have heard about this site and its free resources. I have seen a discount button on the site, for BPP books, however I would prefer to use Kaplan books. I wonder whether the site is able to provide the same discount link for Kaplan books, or has ever offered this, and / or whether this might be possible in the future?
