There are quite a few interesting features tucked away in Pokemon Scarlet and Pokemon Violet. One of these is the ability to buy rare items from an ever changing group of auctioneers in Porto Marinada. This is a small town without a gym, tucked away on the west coast of Paldea. At first glance, this seems like nothing more than part of the water-gym test, but the little town is a great way to get rare items like evolution stones and golden bottle caps that help with Hyper Training. Below we go over everything you need to know about the auction house, how it works, and what items you can buy.

How to Unlock the Auction House¶

The auction house won’t be unlocked until you beat Kofu, the water-type gym leader. During his gym test, you will be sent to the are where it’s located. The auction house or houses are all located inside the small market area in Porto Marinada.

How to Use the Auction House¶

Bidding at an auction in Porto Marinada.

Using the auction house is easy. You will play a simulated auction when you are doing the gym test for the water-type gym. The rest of the auctions work similarly to this. You are told what items each booth is selling. By talking to the NPC at the booth, you can enter the option. You have three options during each bidding phase.

• Bid a High Amount.
• Big a Moderate Amount.
• Bid Nothing.

The NPCs that are bidding against you will gradually raise the price, but you can try to outbid them for a lower amount by waiting and then bidding in on the third choice. It’s up to you whether you think the price you’re paying for the item is worth it or not, as some auctions get a bit high. In addition, you should also note that items like Timer Balls are sold in sets.

Auctions change every two real-world hours, but this can be sped up by moving your Nintendo Switch clock. In addition, if you have saves from Pokemon Legends Arceus or Sword and Shield, you can obtain special items from the auction house.
