Subject: Re: Cost-plus model: COST, IBKR, KMX - any others?
COST and AMZN have more of a membership model, no? Pay a fee to be part of the club to buy your things. I'd say Walmart was more of a cost model, until they tried to follow COST and AMZN into membership. Though they did have Sam's Club which was membership model maybe.


Does Carmax shoot for a $2k profit model on a $120k car?
