When I worked retail sales you definitely saw different return rates on different SKUs. I tried to collect data for a college project but the sample size was too small. (My class was in the spring, and sales boomed in the fall) I was always surprised that the company didn’t do that, as they definitely lost alot of money to shrink and exceptions for high fail devices. At one point the company self-funded warranties, so a lemon had to kill profitability.
