On OurSong, every creation has its own trading market, and all users can engage in buying and selling through "Sell" or "Bid" or "Buy" . You can click on "Buy" in the bottom right corner of the artwork to enter the marketplace for transactions.
Sell: If you are a creator, you can click on it and set the fixed price and quantity to put your creation on the trading market for others to purchase.
Bid: If you are a buyer, after clicking on it, you can set the desired price and quantity you want to purchase and make an offer to the owner of the artwork. Once you place your bid, the system will also notify the artwork owner, and they can decide whether to accept your offer.
Buy: As a buyer, you can simply click on the "Buy" button, then set the quantity you want to buy, and finally select "Checkout". This way, the transaction will be carried out using the price already set by the seller.
