This is an interesting thread. I have a shopify store, using AliExpress and I have to deal with PayPal and Stripe disputes because people don't read the information provided right up front! They also suffer from "buyer's regret" as soon as they purchase and then turn round and say it was "fraudulent", even though they used their own email address and own billing address for shipping
. If they contacted us straight away, we have no problem cancelling the orders, as we are not fully automated and the orders are made manually, so a cancellation within 24 hours is no problem. I have not yet put the shop on Pinterest because I can't think of a safe way to promote it, with the products changing frequently, though I see that doesn't stop people adding Etsy links into Pinterest and them being promoted right round the web, even though the particular item is no longer available. I am currently considering an informational blog, with links to the items but that will take time to set up.
At present, the stuff is promoted through Facebook ads but they are VERY expensive.
