As it's the 30th today I have been to the supermarket to stock up. On the 20th and 30th of each month the supermarket offers a 5% discount to card holders. It's a measly amount I agree but I think if I am going to shop there anyway I may as well get the discount.
I belong to another online group called Frugal Japan where members discuss ways to be frugal, thrifty, save money. I don't always follow their suggestions in fact I am not really frugal but it still makes for an interesting read. Every so often a tip will come up that I am able to put into play.
