But everytime i passby those shop no customers one, not including those in prime shopping malls la, like very remote or secluded areas for example Scotts garden 2nd floor, that area hardly got shoppers walk around. Expenses should be at least 7k a month so how they sell so many specs/contacts to even cover the cost?

And if the margin is really that high, cost rm30 sell few hundred then other shops will be competitive already especially online private sellers.
