Non-delivery in itinerant sales transactions – a transaction where the trader offered to perform the transaction without an order from the consumer, in any place that is not the trader’s business premises or those of his representative. It is not possible to cancel an itinerant sales transaction for the purchase of “perishable” goods. That is, products that, once supplied to the customer, cannot be reused or supplied to another, or products whose value will decrease (or will deteriorate) until they are returned to the trader.
