I don't even know what an autobuyer is lol, I started neopets like 3 weeks ago and i wanna get the full advantage of everything i can lol
there are many programs that can help you make neopoints. autobuyers are programs that buy items from the main neopian shops (usually ALOT cheaper than what others sell for), so you can resell them for higher and make lots of profits. but dont use programs too much / too often as it can get your account frozen forever.
