The secret payment or allowance of rebates, refunds, commissions or unearned discounts, whether in the form of money or otherwise, or secretly extending to certain purchasers special services or privileges not extended to all purchasers purchasing upon like terms and conditions, to the injury of a competitor, and where such payment or allowance tends to destroy competition, is an unfair trade practice, and no person shall resort to such trade practice.
