A time that you saved money for something

Earlier this year, I saved money for a new computer I wanted to buy. Because I've had my old computer for 3 years, it became quite slow, which was annoying. So, I decided to buy the brand-new MacBook Pro. As a university student, I didn't have much money, the computer was a big expense for me. Therefore, I had to be on a budget. This is what I did: I made a plan for how much I could spend in terms of meals. I spent no more than 3000 Toomans per day on my food for two months, and I didn't eat any snacks. Every time I went shopping, I only bought the basic necessities, like stationary and toothpaste. When my friends asked me out for parties, I would politely turn them down, because I know parties meant all my previous savings were in vain. I even kept a record of all my spending on a phone app, so I could better monitor it. Those two months seemed very long, but when I finally bought the MacBook, I felt it was worth the effort.
