Hey Kalmatoro. Well first, an Autobuy is the price that the seller wants for the texture. But the seller is usually expecting a lower offer. Usually they have a minimum bid or offer set. Which means it's the lowest you can offer. If it's an auction and there is an Autobuy, you can pay that price for the textures and get the textures then instead of the chance of someone else winning and buying the head. But the Autobuy will always be a lot more expensive. So you can always pay the extra price to get the textures sooner.
And then someone would pay you for the textures by simply transferring you the tc. And then you would pm them the picture of the textures, or if it's multiple texture you can upload a file to a website and send them a link to download the textures.
