This are the common tagalog words we use when in the market.

How much is this? ---- Magkano po ito? (Mag-ka-no po i-to?)

How much per kilo? ---- Magkano ang kilo? (Mag-ka-no ang ki-lo?)

How much per piece? ---- Magkano ang isa? (Mag-ka-no ang i-sa?)

 

Hope it helps. And also when your in the market always ask for discount because they will surely give a discount. But be careful because some seller in the market increase their price if the buyer is foreigner. So again asked for discount.
