This is a different case -- usually in this, it not that the retailer would not accept the item back; it is the manufacturer trying to prevent you from asking the store to take it back, as the store would then charge the expenses to the manufacturer. If the manufacturer thinks a customer are missing some parts (for whatever reason, even if they broke them yourself) they will ship extra parts to avoid dealing with the store.
