USA like rice (like Japanese, chinese, taiwanese short grain) is much cheaper at Amazon Supermarket (Amazon Fresh brand)
I agree with this 1000% after being in Hawaii and other mainland states like you. It was very esay in the USA to spend NT$1000 at the supermarket. The cheapest thing I got was Amzaon brand Japanese/Taiwanese rice apox NT$75 per kg. (I like the Amazon Fresh markets, something new) [4954] ˉ
