Questions

Which marketplaces does BuyLow AI compare for Apple iPhone Duo?

The snapshot pulls Craigslist and Swappa, plus Mercari's public search and Vinted's catalog when those pages respond in time. eBay is included when a Browse API key is set. OfferUp, Facebook Marketplace, Amazon, and the other deep-link marketplaces stay as links to their own search, so this page does not copy their listing text.

When were these prices last updated?

A fresh snapshot is taken when this page is requested, then kept for up to 12 hours.

Can I sell a Apple iPhone Duo on BuyLow AI?

Yes. The sell quote for a Apple iPhone Duo shows the best buyback offer the app has for that model. This page links to it instead of starting a second price fetch.
