According to Yahoo Finance, Costco is selling cars to its members. But, then it states that Costco works with auto-buying service.
I think actual buying process is the same at authorized dealers, but with pre-negotiated price for Costco members. The price may be lower than MSRP, but may not be as low as a good negotiator can get.
"It works with an auto-buying service to negotiate the lowest prices.
The retailer has a huge advantage over traditional car dealerships: It doesn't need to make money from the cars it sells.
Because of other income streams including membership fees, groceries, gas, and apparel, Costco can afford to sell its cars for lower prices than competitors can."
