Costco's $60 annual Gold Star membership pays for itself if you spend $50/month on bulk groceries and household items, which most families do. For non-grocery shoppers or those visiting fewer than 10 times yearly, Best Buy's no-membership model may provide better value despite potentially higher per-unit prices on selected items.
