Purchasing via Shopify is not advisable.
Thinking of an alternative to ebay or amazon, you can buy through Shop (changed to Shopify) and select and pay for items which are posted from “stores”.
By the time the confirmation of order arrives, the money is charged and the store disappears.
Shopify allegedly support takes days to respond to emails (no other options found functional) to say that you must contact the store. Shop/Shopify promotes stores which steal your time and money.
