I must buy $50/mo in household products to receive commission on my referrals purchases. Can 100% be deducted?

I'm a customer of a wellness company. I buy all toxin free household products from them and refer new customers to them. When my customers (and their customers for 7 generations) order, I receive a minimum of 7% commission on their purchases. Since I must place a montly order of $50 to keep this benefit, would I be able to write off all my household products of $50 * 12mos = $600 for the year?
