Haechans power is so amazing because his things sell out relatively fast! From concert items to album covers, fangoods etc... the demand for haechan is high!!
the signed poster, hologram pc and birthday goods are just a few examples
I remember his griptok sold out like lightening as soon as it was released.. sm had to quickly restock
sm needs to pay attention to this
not anything offical but when haechan was seen wearing this jersey it sold out in the blink of an eye
another example.. this hoodie sold out as well 
It was even more shocking that it sold out in multiple online stores not just 1
