So a lot of what's left as a regular user are scams or simple resellers. Amazon also has a lot of the "garage sale" type of stuff these days
In my previous searches of Etsy so many of the results were comprised of cheap (originally), mass-produced products masquerading as 'hand-made'. Peppered among them are actual hand-made or vintage goods but I'm not sure if Etsy was intending to address such listings, though things may have changed from when I stopped browsing (a couple years ago).
Back in the day, before aliexpress, it was good too because you could rip off the sellers. Just claim the thing never arrived and since for cheap stuff they had no tracking numbers the seller always had to refund you. You could get TONS of free stuff that way. Now aliexpress does this right and it's significantly harder.
