Pokemart and the Global Marketplace

The Pokémart is a convenience store often characterized by its blue color. Almost all towns across every region has a Pokémart. Inside the Pokémart is a vendor which sells many essential objects such as potions and poké balls. It is also the only place to access the Global Marketplace.

Vendor Items
Items sold by the vendor depend on the location; some areas (especially the beginning towns) do not have as much items.

Global Marketplace
The Global Marketplace (GM) is a player market filled with items and Pokémon up for sale or auction. You can buy, auction, or sell items and Pokémon here -- there's a tab for each in the upper left.

Auctions
Auctioned items and pokemon are on the market for a limited time, highest bid at the end of the time limit recieves the item. Money is refunded if someone outbids you. If you are online at the time, a message will show in chat saying that you've been outbid.

Buy
Allows you to purchase items or pokemon that others have put up for sale.

Sell
The default tab when GM is opened. The sell interface allows you to sell items from your inventory or pokemon from your party. A listing fee is charged for any item put up for sale. The fee is based on the sell price of your item, but this fee is NOT refunded if you cancel the sale.

Notes / Tips
In order to see anything in the buy or auction tabs, you have to click the search button in the upper right.

Anything bought in the Global Marketplace go to the Item Box interface, accessed from the button in the lower right of your Inventory screen.

Search for Pokémon of a specific level by adding a number in front of the Pokémon name (example: "100 Gengar").

Search for Pokémon of a specific nature by adding a hyphen followed by the desired nature (example: "Gengar -Timid").

There is no way to search for a pokemon's ability or IVs.

You cannot purchase Pokémon with higher levels than the highest level of your current Pokémon (example: you can't buy a Level 100 Gengar if your highest leveled pokemon is only Level 30).

Some items, like HMs, cannot be bought or sold on the market.
