@PNS the ability to return retail goods really started with Montgomery Wards in the early 1900s. Even before Sears, Wards invented the catalog order book and pioneered USPS delivery to rural homes (not just to PO's) with his 4-in thick catalog offering 100% satisfaction guaranteed. Before that rural people had to bulk buy in an annual big city trip and haul it all home with no returns. This of course requires a high trust culture which India is not.
