cybermat, we humans who came you before devised systems that deal with just this problem. We called them "shops", and later as we became more advanced enabled them through something we call "internets"
one of the internets is called "amazon". they will sell it to you and deliver it, verily, to your door after you pay for it.
Another is called " steam". With them it appears magically (or perhaps demonically) on your computer after you pay for it.
Please advise if you need help with learning about "paying", it relates to another strange human technology devised long ago.
