The board may suspend without prior notice a distributor’s privilege to purchase stamps or meter register settings on the deferred-payment basis or may reduce the amount of permissible deferred-payment purchases fixed for the distributor, if the distributor fails to promptly pay for stamps or meter register settings when payment is due, if the bond or bonds of the distrbutor are canceled, become void, impaired, or unenforceable for any reason, or if in the opinion of the board, collection of any amounts unpaid or due from the distributor under this part are jeopardized.
