You say you were not using a vpn. Then the site has your ip and probably has meta/google ads or other shit running on it and links the product with your ip.

This data is added to some data broker/ ad network and you see an ad when you visit a site using this network as you have "signalled" interest in the product by viewing the product page the first time.
