I found my lost wallet about a week ago, and I learned something by that. Which is:
"I did not need my point cards."
You can save some money by using the point cards of the stores.
Every time you purchase at the store and let them scan your point card, they give you some points depends on how much you purchase there. Like when you purchase 50,000 yen total at the store, they give you 500 points which worth 500 yen value.
But,
- The point you earned can be used only at their store. (There are some cards, you can get/use the points at any stores wherever they accept their point card, but I've heard the rumor that they are correcting those purchase information for whatever the reasons. Which sounds little creepy to me.)
- You have to carry the bunch of point cards all the time. (Well, you don't have to. But I tend to forget the point cards whenever I go shopping at the stores. So, I carry all of them pretty much all the time in my wallet; but it takes too much space there.)
When I did not have those cards after I lost my wallet, I keep refusing those points offering from the stores. It takes about 4 times refusing average before they stop asking me the point cards.
It was like:
1st time:
2nd time:
3rd time:
4th time:
5th time:
I feel like I beat their system after they stop asking me the point card, but at the same time, I miss them asking me if I have point cards.
