Weight is measured with kilograms in Turkey like in Europe, unlike pounds used in America. Some sentences useful for buying fruits and vegetables would be:

Sentences for request:

    A. Bir kilo domates alabilir miyim? (Can I get one kilogram tomatoes?)

    A. İki kilo elma verir misiniz? (Can you give me two kilograms of apple?)

    A. Yarım kilo çilek alacaktım. (Something like "I would like to buy half a kilogram of strawberries.")

Possible response of the seller:

    B. Tabi, buyrun.(Sure, here you are)

    B. Hemen. (Immediately)

    B. Buyrun, afiyet olsun. (Here you are, good appetite)

Reply to the seller before leaving:

    A. Teşekkürler. (Thank you)

    A. Hayırlı işler. (Something like "Have a fruitful work day")

    A. İyi günler. (Have a nice day)

Another point worth noting if you are in Turkey is that bargaining is very common :) You can buy many things under the display price with some bargaining. However, this is not true if you are shopping from a supermarket where you buy things and pay to the cashier.
