Delivering unordered goods is a passive way of selling where a trader takes a gamble that you might decide to keep and pay for the goods. Usually unordered goods are books, periodicals, CDs, audio or video tapes.
You do not have to buy unordered goods. You can store the goods in a safe place and wait for the seller to collect the goods. If the seller does not collect them within three months of their delivery they become your property. Alternatively, if you don't want the goods you can write to the seller and tell them that you are holding items that they delivered that you did not request. You should also provide the seller with an address where the items can be collected. If the seller does not pick up the items within one month of you sending the letter, then the goods become your property.
Keep a copy of the letter that you sent the seller and if possible send it by registered mail so that you have proof that the letter was sent. If the seller wishes to collect the goods within this timeframe and you refuse to let the seller take them back, you will have to pay for them.
