[Unanswered]  Where to find Beys in Bangkok

I am going to Indira Square in Bangkok today and do we get real Beys there? If no please recommend some other shops and today we reserved the day for shopping. 
I went to Phuket's Central and Jungcylon Mall and found beys upto ChoZ Customize set but while comparing it to water which is 20THB I felt it expensive and did not buy
So which shop is recommended for Beys.
Thank you in advance

I am in Bangkok now.
Does MBK have Beys?
