To Snap Up
That's an informal idiom that means to quickly and eagerly acquire or purchase something, often because it's perceived as a good deal or because it is in high demand. When someone snaps up an item, they get it quickly before the others have had a chance to do that.
It's about being quick, being decisive and taking advantage of an opportunity. Here's some examples.
