The context
Consumer electronics is a structurally low-margin sector dominated by price wars against Amazon and large retailers. Catalogs are wide, cost of goods (COGS) accounts for most of the selling price, and ancillary fees (shipping, returns, support) weigh heavily.
In this context, steering by revenue or simple gross margin rate is not enough. Two products sold at the same price can have very different net margins depending on their weight, return rate and shipping offer.
