Money is always a big thing. You’re already at the point where you’re committed to spending too much. That doesn’t mean wotthehell wotthehell, double down and carry a bunch of debt on your credit card. Nevertheless, buy whatever you think is best — even if it’s $50 more than your second choice and $100 more than the limit you imposed on yourself last week.
The regret of overspending lasts until the next paycheck. The regret of buying something you didn’t like lasts as long as you own it.
