People just don't drink enough real coffee for us to have a competitive market. Most people just drink instant coffee, especially in the provinces. In Lima you would have more options, but still, like so many other things, the prices can be equal or greater than they'd be in the US.
I just make do with Cafetal, which you can get at most bodegas (at least in Lima) and a small percolator from Vietnam (phin). A percolator you can get a market, it's called a cafetera. Cafetal is strong and flavorful enough to pass muster and for sure beats instant coffee. Creamer though... that's a tough one. If you find heavy cream, you could mix it with whole milk to make your own.
