Can AI help me compare Amazon, Walmart, and Costco prices?

Yes, AI can help you compare prices across Amazon, Walmart, and Costco, but Costco is usually the trickiest of the three.

How AI can help

• Amazon and Walmart: AI shopping tools can often find and compare public listings quickly.
• Costco: AI may have a harder time because Costco prices are often behind member access, and prices can differ by channel or location.

Important Costco caveats

• Some Costco prices may be hidden behind a member login.
• Costco online prices can be different from in-warehouse prices.
• Some AI tools may pull Costco pricing through third-party sources like Instacart, which can include a markup, so the displayed price may not match Costco’s own warehouse price.

Best way to use it

Ask a tool like Copilot, Gemini, or another shopping assistant:

“Compare the price of [product] at Amazon, Walmart, and Costco. Tell me whether the Costco price is online, in-store, or from a third-party delivery source.”

That matters because Costco pricing can vary by channel, and the final price should be verified before buying.
