I get several SOLD items a day showing up in my views and searches. I don't think it is an issue so much.
When I am building Treasuries, invariably within Etsy, items coming up under "Items matching your Taste" are sold when I go to them.
If someone comes to my shop via a sold listing, hopefully they will still peek in at other listings. Because I do Vintage and handmades, I can't relist a vintage piece .
It keeps me busy!
