Cash for beer

No wholesaler may sell beer to any retailer except for cash. Cash shall include a check dated on or before the day of delivery or an electronic funds transfer initiated on or before the day of delivery. Any wholesaler receiving a check from a retailer which is returned by the bank due to insufficient funds shall immediately notify the retailer. If the check is not made good within forty-eight hours, the wholesaler shall notify the wholesaler's competitors and the tax commissioner. No sales shall be made to such retailer until the wholesaler notifies the wholesaler's competitors and the tax commissioner that the insufficient funds payment has been cleared.
