Watermelon!!

Do you like watermelon? I do! Do you eat the seeds of a watermelon? I do!! Really!! It`s annoying to spit out each seed, so I just swallow them. But what is the deal with the price of watermelon, and some other fruit, in Japan!? Somebody please explain it to me! The price of some watermelon, for example the kind sold in a department store or some fruit shops, is CRAZY EXPENSIVE!!! WHY??? I don`t understand! Also, melon, peaches, grapes...it is endless! I used to eat a lot of fruit when I was a child. I ate fruit every day. Now I don`t eat so much, sometimes an apple, or banana...I wish the price of fruit was cheaper in Japan! Then I could enjoy fresh fruit every day like when I was younger ;)
