Buying Pokemon Sun & Moon Munchlax, possibly with Yawn learned

[Baroque]

Sooooo I'm kind of a Poke-Noob, as it were... I didn't know Snorlax didn't just naturally have Yawn. So my Munchlax is level 22 and I still haven't evolved it yet. I read that the move relearner is just before the Elite 4, too? I Don't want to wait that long... so, if you have a Munchlax that isn't level 20 that you want to hoard off (Or maybe a Snorlax that did learn Yawn and isn't tooooo overlevelled) then I'd buy it. Name your price.

I'm rather confused, I just got this Pokemon from the wifi event today. It's still level 5, do you want it? For how much.

You can get it for free by receiving it as a mystery gift.
