Featured Selling Guidance as a Jewelry Dealer

I asked a similar question the other day. I used to do very well on Ebay and this past year when I started selling again after a few years I only sold one postcard. It's very discouraging because I see similar items selling for more than I've listed mine for. The algorithm was the answer I got as well.

Now I have to ask - what is 'vide grenier'. I looked it up but the answer was in French.

 

Vide grenier means empty attic or attic clearance. It is a flea market where private people sell stuff they no longer want, although in many cases professional sellers have stalls as well.
