# Purchase your NFT Once you’ve found an NFT you like, you can buy NFTs for a fixed price or you can buy them in auctions. **Buy now** NFTs listed to “buy now” are listed at a set price. They can be purchased any time during the sale period and without any additional involvement from the seller. This is the simplest method, and is a lot like buying on other e-commerce websites. **Auctions** When an NFT is up for auction, potential buyers can bid on the item. The NFT will either go to the highest bidder, or the seller can choose to accept any offer during the auction. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
