We were hoping this was some sort of shop built into marketplace that was curated or searchable or something, since we've had some success selling on there, but it's a complete garbage pile and dealing with people is awful and doesn't scale very fast. People flake out like crazy, no way to manage messages well or anything. Missed opportunity.
Maybe for Instagram, having a shop built into your profile could be awesome instead of saying, "link in profile" then having your user search for the product they say starting at your site homepage.
