Frequently Asked Questions

Costco typically offers 15-30% lower per-unit prices on bulk groceries due to high-volume purchasing and lower overhead costs. However, Amazon Fresh and Whole Foods (owned by Amazon) offer competitively priced items with delivery convenience. For non-perishables bought in bulk, Costco's Kirkland Signature brand provides best value; for fresh groceries with delivery, Amazon Fresh matches within 5-8% of Costco's warehouse prices.
