Is 290,000 KRW for Mounjaro a good price?

The local internal medicine clinic's prescription fee is 20,000 KRW,
and the pharmacy is charging 290,000 KRW for 2.5mg, while 5mg is 390,000 KRW.
Is it worth trying?
Wegovy starts at 239,000 KRW.
I'm thinking of taking it to save on late-night snack costs.
