Steam payment HUGE price increase!

And I work in the office, so that meal is for dinner and weekend.

I don't mean this to be rude, or against how you spend your money, but out of curiosity, do you buy your lunches when at work?
If so, something that could help you save money(as it's something I do as well) is instead of making just enough food for you and your wife to eat for dinner, maybe make a bit more(enough for a lunch meal), and take it to work and eat that for lunch.

Since I don't really know your living conditions/facilities at work, I can't say how feasible it is, but it is a way to save even a small amount of money a day that you could use to put towards the subscription(and yes, I agree it is wrong that they didn't notify of the increase before it happened).
