Open your mouth because I'm going to spoonfeed you so you never have to ask again.
Step 1: Grind the Festival Plaza to rank 8 so you can request stores from others.
Step 2: Find someone who has Treasure Hunt ** as their favorite shop, and VIP them. VIP a few of these players in case one of them changes Treasure Hunt to anything else.
Step 3: Buy their Treasure Hunt for 100FC and place it in your first spot. Go to it and get a bottle cap.
Step 4: Replace Treasure Hunt ** with any one star shop from another player, or from Sophocles after leveling up your plaza rank, which will cost you, respectively, 150 or 100FC.
Repeat. If you're at a low level it's a good motivation to keep you leveling up.
