I can't answer that for today. But there was a time when they had a very active shopping site -- they were an earlier version of Amazon for 3rd-party merchants, Shopify or Etsy where anyone could open a "store". And Yahoo handled payments, as I recall, just like Amazon does now. I bought many things from there.

Where is that today? Gone, I guess. But it could have been an Amazon or Shopify.

They also had a lucrative ad business. Gone now, I think.
