I began selling on Ebay 12 years ago. I still have an Ebay Store, Etsy Store, 2 Ecrater Shops, and Pinterest, of course.
Sandy's Gingham Country - Ebay Store
Sew One Pretty - Etsy Store
Sandys Gingham - Ecrater Store
Sewingsupplies-plus - Ecrater Store
I've also sold on Bonanza, Wagglepop, Plunderhere, Blujay, iOffer, and too many others to mention. I think the best sites always survive while the others eventually fail.
Sellers know what they like and that's where they stay to "sell" and "buy."
My belief is: "SELLERS ARE THE BEST BUYERS"
