The entire big box economy is a big honking subsidy to people with cars living in the suburbs by the poor, the singles, the seniors, the urban, the cyclists.
It only works because of the highways and the parking lots and the infrastructure paid for by everyone (road taxes do not cover the cost of the roads) and enjoyed by the drivers. The companies charge twice as much for small packages as big ones because they can; the purchasers without cars and access to the big boxes, the ability to drive between the Walmart and the Costco and the Price Club, don't have a choice.

They extend warranties on electronics for an additional year. If the manufacturer can't help you with an issue, and then Costco support can't help you either, they will refund you the entire amount with very little hassle and make the manufacturer eat the cost. If you're unhappy with the other products they sell, they'll also take the products back with almost/no hassle.
