susah memang susah.
as i say if the item is mass production . everyone are selling same things.

my each parcel send out is rm30-48 perparcel. my profit margin from RM15ringgit drop until RM2-3ringgit.
sometimes even negative. therefore i memang tak tau how much i lose.
last week purposely check all the account . then find out 15k lose until this moment. wakao.. no wonder my bank amount became less.
kesian mau nangis
