Cheap high proof liquors?

As the title says I’m wondering what cheap high proof liquors are out there. Money has been tight lately so I’ve been budgeting my alcohol intake, and rather than drinking things I enjoy I’ve been focusing more on ABV, more bang for my buck. Anyways I’ve tried Cruzan hurricane proof which is 137 proof, and I’ve tried Smirnoff’s 100 proof vodka. Just curious what other options that are out there I could try out. For price comparison I pay about $20 for a 750ml bottle of the Cruzan and around the same price for the Smirnoff.

Edit- apparently underage people are common here so just to clarify I am 21, birthday was December 9th 2003.
