Would it be unethical to buy cooking wine to save money?

I just found out that my price chopper sells 12 oz bottles of cooking wine (18%) for only around two bucks. This kinda surprised me because it costs less than cheap beer from a sketchy gas station where I live.

I tried to look it up to find anyone talking about this, but the search results were scarce. The worst thing I can find on it is the salt percentage (1.5%) but if I can manage to get it/keep it down would there be any problems? I’m curious to see if anyone else has done this before.
