I think additional printings are based largely on how sales of a given product have gone over time - i.e. if something consistently sold well and looks like it would continue to do so, they're more likely to give it another print run.
Note that a product not getting another print run doesn't mean it sold poorly or anything. They just may not believe there will be enough additional sales to justify it.
That said, since there's really no way to predict what'll get printed again and what won't, it's probably fine to buy it from somewhere else. Paizo still benefits from that, after all. ^^

Yeah, do what you need to do (legally, please) to get the books you need.
I suggest checking with the closest hobby games store and seeing if they have it in stock.
We'll reprint Ultimate Campaign, but a few other books are in the reprint line ahead of it, so if you need the book soon, there are better places to get it than here. At least right now.
Sorry about the inconvenience.
