We want to buy Greyhound with Tom Hanks, we do not have internet, nor can we buy as we are in an area that is not able to receive internet. We tried and all we got was buffering. How can we purchase this movie?

Currently, Greyhound is only available by streaming over the internet and requires an Apple TV+ subscription to do that.

Apple just announced that Defending Jacob, another Apple TV+ streaming exclusive, would be released to DVD. That DVD can be purchased at Amazon so there is at least a remote possibility that Greyhound might be available at some point in the future -- or maybe not.
