Muse can't compare prices on Amazon
He asked Meta Muse to compare a Facebook Marketplace listing with the new price on Amazon. Muse said it can't go on Amazon because that would break Amazon's conditions, but that Walmart, Home Depot and Lowe's work. This matches the news: GeekWire reported in September 2026 that Amazon cut Muse off with a popup saying continued access by an unauthorized AI agent violates Amazon's Conditions of Use, and CNBC reported on November 1 that Amazon, Kohl's and Neiman Marcus, among others, have moved to block personal agents like Muse.
The lesson: Amazon blocks Muse, so check Amazon prices yourself and let the agent cover the other stores.
Copy this prompt
I'm thinking of buying [ITEM] on Facebook Marketplace for [PRICE]. Compare it with the new price at Walmart, Home Depot, Lowe's and [OTHER STORES YOU CAN REACH]. Tell me which stores you couldn't check, so I can look at Amazon myself. List the condition and age I should ask the seller about.

Watch out for
- Ask the agent which stores it couldn't check. Otherwise the cheapest option can be missing from the comparison.
- More stores are blocking personal agents. Expect gaps.
