This is a repost of what i did few years ago. I would like to share with you all how to buy things in Japanese.
すみません. (Su-mi-ma-sen/ Excuse Me)
これ/それ/あれ を ___________ ください (kore / sore/ are o ________kudasai )
Give me _________ of this/that/ that thing over that (far from you and the listener)
これ: ko-re /this
それ: so-re / that
あれ: a-re / that thing over there (not near to you or listener)
ひとつ: hi-to-tsu/ one
ふたつ: fu-ta-tsu / two
みっつ: mi-ttsu / three
よっつ: yo-ttsu / four
これ を よっつ ください。 (kore o yottsu kudasai/ Give me 4 of this)
それ を みっつ ください。 (sore o mittsu kudasai/ Give me 3 of that)
For different items, there are different counters. For now, you can use the above first. We will learn more later. (^_^)
Usually Japanese will take the calculator and show you how much you need to pay.
