actually sentul / jalan ipoh area.. should be more than enuf.. price is pretty reasonable too
i just got mine.. 2 boxes. but ended up .. contractor said no need to use it :s

last time i bought around rm 2.5 for mml tiles.. well, the price depends on quantity and design too )
try to talk to the employer there <bangla / india> nego a bit. they will sure be able to reduce somemore

hmm.. how many tiles we are talking about ?
sometimes, they do not have the sufficient tiles there and might need to wait..
since i bought 2 boxes.. i took it back myself..
in ur case if it involves more.. try to nego with them )
