I sold my ex-smartphone on Merukari.
It's sold 9,900 yen!
Before, I have taken out a 24-months loan for my ex-smartphone.
The payment was 1,000 yen a month and left 8-months loan.
So I can add the sales to my loan!
I was very satisfied!
PS : This book, under below, is very useful for keeping a diary!
I recomend it to you.
