QUESTION : What if link above me doesn't work or using the title finds 3 items?
If link of shop above doesnt work, it is not your fault. It is on the shop above to be sure they post a good link to fave their item.
If there are more than one item from the same shop of the link above for you,(which usually it is), choose any item from that shop. There should just be items all from the same shop.
If more than one shop show, then shop above did not post a good link. In this case chose an item belonging to shop above.
Some shops put the same title for more than one of their items.
