I have made a lot of credit cards because of the points and special offers. It is true that you can get the most out of them if you use them at different stores, but it is very cumbersome to carry around a lot of them and have to think about it all the time. However, the benefit is only a few tens of yen, so I have reduced the number of credit cards to two.
I feel very good because I no longer have the risk of losing them or accidentally incurring an annual fee.
I left Rakuten Card and Amazon Card.
I concentrate on my Rakuten Card for everyday payments to earn points.
I have decided to consolidate my Amazon purchases and business-related expenses onto my Amazon card.
