I did see on discogs that people were getting full refunds without having to return the item...
They pointed to the T&C on the WASTE website which says in section 1:
LIABILITY :
- a) If the Customer establishes that any of the goods have not been delivered, or have been delivered damaged, or are not of the correct quantity, The Company shall at its option, replace them with similar goods, or allow the Customer credit for their invoice value.
b) If the Customer establishes that any of the goods are defective The Company shall, at its option replace them with similar goods or allow the Customer credit for their invoice value.
c) In no circumstances shall the liability of The Company to the Customer under this condition exceed the invoice value of the goods.
