I take it you're not in the US? Retailers here generally must warrant against DOA, but almost anything beyond that can absolutely be shoved off onto the manufacturer.

Those who wonder why Americans can get so many things so cheaply - yes, we have lower tariffs (or at least did), but also we don't have those minimum-duration warranties that allow the consumer to return to the place of purchase as much as a year or more after purchase and demand satisfaction from the retailer. Those are expensive to provide.
