Interesting, Okay cool, so I'll email Monoprice and ask them about it.
Just wanted to make sure it wasn't me storing it or doing something wrong with it.

Well, who would've thought, Monoprice is replacing the filaments free of charge.
I love companies that stand behind their stuff.

If you bend PLA and then keep it bent under stress, then microcracks may grow, and they may keep growing until it snaps. This can happen when it is sitting in the feeding traject for a longer time. So it is best to unload it after printing, and store it under no load. As it gets older, it can become harder and brittle too. Moisture also degrades PLA, it breaks down the molecules, so that could also speed up the brittling-effect. But I haven't had it snapping while printing or while in the feeding traject yet. So, in your case, it could be a bad batch or bad brand too. Wood, stone, carbon, or metal-filled filaments are also more brittle.
These are microcracks after I bent the filament in the opposite direction for a few seconds, and then released it again (=removed stress), to make bending radius less tight and reduce friction in the bowden tube and nozzle.

These are cracks growing in a keychain carabiner hook, due to repeatedly opening the hook. A few times more, and it would totally snap.
