Does anyone have a Product Alliance Interview package discount/referral code or want to split the cost?

Hi guys, just decided to buy the Product Alliance interview course since my last few interviews didn’t go well. Does anyone have a referral code that I could use, or is interested in splitting the cost together? I’m not unemployed right now so want to minimize the cost! Thanks!
