# Tips for trading on the marketplace
### **To buy an item:**
* tap on the selected item and the currency (if it is possible);
* click the ‘*Confirm and buy*’ button;
* if you have enough $WLKN tokens to complete the purchase, the item will go straight to your ‘Collectible’ (it may take up to 10 min);
* then you can continue shopping or open ‘Collectibles’ and check the purchase.
### **To sell an item:**
* selected item that you want to sell and click the ‘**Sell**’ button;
* enter the *price* and select the *currency*;
* press the ‘**Confirm and sell**’ button;
* your item is already for sale and as soon as someone buys it, you will immediately receive the tokens .
**To use the item purchased:**
* open ‘**Collectibles**’ tab;
* select a CAThlete;
* scroll down and tap on a *slot* with the item category you’d like to put on a CAThlete;
* select one from the items available and click ‘**Save equipment**’.
## When trading on the Marketplace, keep in mind the following:
* All transactions in the Marketplace are ***processed on the blockchain*** and therefore may take a bit **more time to process** than usual. It may take up to several minutes for the transaction to be *verified* and for the NFT to be *transferred* to you.
* You may buy or sell NFTs for **SOL** and **$WLKN** token, so **double-check the price for which you are selling the CAThlete\Item**. If you make a mistake and NFTs are immediately bought, it will be **impossible to cancel the action or refund the payment**.
* There is a 5**% commission for selling any NFT**, plus the **gas fee** taken by Solana blockchain. Please note that if you change your mind and *remove your NFT from selling*, Solana will also *charge the gas fee*.
