Because of this thread, people go to less established, newer shops like Adix or Kasia instead.
They are all probably friends though, so heck.. as consumers we have different preferences, some want better price, some want better service

The shops compete on different points as well.
Like why people went to MS to hoot N3 despite J2 selling cheaper, MS got better reputation and is more popular among people.
Same like ST and M1, ST more expensive, M1 cheaper but people still go ST for supposedly better coverage while others just go for cheapest M1.
