These days, the cost of living is increasing.  I'd say this rapid hike is caused by the war, the climate change and things like that. 
 Much money flows out of my wallet.   
So I have started ポイント活動.   ポイ活 means correcting reward points through shopping.  I save up double points using creditcards and storepoints at the same time.  Sometimes, however, I use coupon of my smartphone's apps.  That means getting triple points.   That's why I can accumulate more points than I expected.    
Using points, I can buy other things at a discount.  For example, I often use them for gasoline. Now that the gasoline fee is relatively high.  
If it were not for the inflation, I would not try ポイ活.   
It's a fine resistance as one citizen or one housewife.
So everyone, How about trying ポイ活？
Thank you for reading.
