Isn't warranty provided by the manufacturer and not the retailer, and hence better to buy big ticket items online (likely cheaper since there is no local retailers markup). Even for clothes, yes offline stores do give us the ability to ability to try, but online offers more choices, colours, fabrics, sizes and brands than any one physical clothes store could possibly offer, so I do think online has an edge.
