comparison order benefits if you're buying 4 vers:

Mymusictaste 103.81 USD (shipping included):

*note: i'm not sure if there's total 2 pcs, or will there be variation of pcs. as of now, i'm leaning towards they only have 2 total. Since during #, they had 11 pcs total and they did show it

i'm only do 3 sites here because those seems to be the best option for pricing and benefits

check this thread out if you wanna know what charts are these sites counting towards (and details from other sites apart from the 3 i did): https://twitter.com/kimhyjs/status/1315493724449837057
