They don't always remove features. Really it's more about making the comparison between the products just fuzzy enough that the other retailers can't give the manufacturers a hard time for offering Costco a cheaper deal. And in some cases just trying not to devalue their brand elsewhere. Costco doesn't sell the same Dyson vacuum as everywhere else -- instead of a "Total" they sell an "Absolute" or some other equally confusing nonsense. The difference is they remove a single (non-motorized/cheap) attachment, and throw in two different ones and a couple other accoutrements. And sell it for $100 less. The part that's not included in their package can be purchased retail from Dyson for less than $100. Other retailers can't use this to put pressure on Dyson. Dyson doesn't look like they're overcharging everywhere else.
