Please settle a family disagreement...
If you order an item from a retailer and they send you the wrong item (e.g. a more expensive item) do you LEGALLY have to return the item/does the retailer have any legal standing to retrieve the item/compensation for the difference in cost?
I'm not talking about the moral side of whether it's right/wrong to keep the item (most of the parties involved agree on that!), but the legal standpoint.
YANBU - legally you cannot keep the item
YABU - there is no legal action that the retailer can take
