1. Post an item from your shop
2. Look at the 10 items posted before you. Pick 5 and favorite them.
3. Only post 1 item at a time. Wait for 10 items posted after you before posting again.
This game gives you a 'quality report'. If your item is irresistible you have the chance to get 10 favorites. If you get a low number of favorites on this item you know you need to work on the quality of the listing.
Enjoy!
