for me,i always browse every shop in lowyat before i buy something.i helped a friend bought an SE phone,helped a friend and my sister to buy laptop.so far nothing bad happen.

my tips to buy things from lowyat:

1) search everywhere you can.
2) try to ask best price.if the seller said they can give discount till ridiculous price,better leave it.i've been offered SE k810 at rm6** when RRP is RM8**.i left the seller cuz i know that's ridiculous.
