I assume those aren't US dollars? My suggestion is to go on a classifieds site and find a bargain there. You can find 2x8GB SODIMM DDR4 for like 20€ in Germany, because it's the default configuration for laptops and people are buying aftermarket RAM to upgrade to 2x16GB leaving a glut in 2x8GB configurations. Something similar happened to the desktop DIMMs but to a lesser extent because you can put four of them into a PC.
