I pin most of my stuff on pintrest. I got a lot of repins, but because people rarely tell you how they find your shop or item, I don't know if it is increasing my sales. I think it is, but sometimes I think people just repin to copy it them self. Oh well. Im glad they like my items regardless. I wouldnt worry about keeping the pricing up to date, or if the item sold, too much to deal with. Keep pining on pintrest, it can't hurt. As for changing them into sales, take good pictures, keep your pricing fair, fresh, and new, charge a fair shipping price, ship international, especially to Canda, you can go to USPS website and look up shipment cost to anyplace in the world, I keep a chart of all places I ship to, so I can easily list a shipping price. Ship by weight, not just some random amount. The other day i saw a head band which probably weighed less than an ounce, shipping to the usa from the usa for $6.00. And she asked why her sales were low. Hope this helps.
