Costco: the membership changes the retail choice
For shoppers who can use a membership warehouse, Costco offers a selected merchandise range at value-oriented prices, supported by buying scale and cost control.
Observed: Costco describes its membership model, selected range and policy of keeping costs down for members.
GYB reading: The membership and selection are commitments, not decorative personality words. Suitability depends on the shopper's needs; the source does not prove every item is cheaper.
