Goods that fail to conform to the contract at any time in the six months after delivery are taken not to have conformed at delivery, unless the transferor establishes that they did conform then, or the presumption cannot sensibly apply given what the goods are or how the non-conformity arises. The retailer, not the consumer, therefore carries the burden of proof for defects that surface in the first six months, and warranty and returns processes must reflect that.
