An order must be delivered within the agreed period or not later than 30 days after the vendor has received it. If an ordered good or service is not available, the vendor must announce this as soon as possible and return the price you have paid within 30 days. If this is not done and the Finnish Consumer Protection Act is applicable, you are entitled to demand interest for delayed payment as provided for in the Interest Act. The vendor may include a clause in the terms of contract allowing him to supply a product or service that is different, but equivalent and at the same price. However, if this is done, he must say so clearly and also inform you that he will bear the costs of returning the product if you decide to exercise your right of cancellation. If delivery of your order is delayed beyond the agreed date, you can specify a reasonable extra period within which you demand delivery. If the vendor does not deliver the order within this extra period, you can demand that the contract be dissolved and the money you have paid be returned.
