I save up for a thing so I have the cash, but justify the expense to myself by dividing the enjoyment factor over the time I own and use the thing.
I outright refuse subscriptions, I love geoguessr, and will buy giftcards for a year or two when I have the money, and then not worry about it, if I don’t have the money next time, I will simply let it run out, and wait untill I have money for a gift card.
