Haggling prices in markets

Even in markets you will usually see the price on a sign.  If it seem reasonable I don't bother to haggle over a few baht.  Wholesale prices can vary from day to day and it can be difficult to keep abreast of market forces so if you really want it, just buy it.  If you buy enough of something you might be able to ask for a bulk discount.  Instead of reducing the price they sometimes through in a little extra without charge.  In tourist areas I guess you should expect to pay a bit more than elsewhere.

To be fair, I speak Thai so probably receive preferential treatment.

It doesn't hurt to ask, especially if you make the offer in a playful mood.

Thanks Dick for the reply. I will keep that in mind. Do you practice this? many thanks, Brian.
