There are a lot of things people get wrong about earning credit card points. Some people obsess over welcome bonuses. Others think cashback beats points every time. And then there are the people who believe all business cards are basically the same. I don't agree with any of that. There is one card, however, that I think is in a league of its own if you're spending serious money on advertising. The Amex Gold. For a long time, it feels like a cheat code. Every dollar you put into ads keeps stacking points, month after month, and it's easy to think that's just how it's always works. Until it doesn't. What almost nobody realizes is that Amex quietly caps the 4x earning rate after $150,000 in eligible spend. From that point on, you're earning 1x. No announcement. No celebration that you hit the milestone. Just a fraction of the rewards you were getting before. Most advertisers assume that's where the game ends. It isn't. It's where the game changes. Once you understand how people who spend millions on ads think about their credit strategy, you realize there are ways to keep maximizing rewards long after you've hit the cap. It's not something Amex advertises, and it's definitely not something most business owners know. But if you're spending enough to run into that ceiling, it's worth knowing before you leave thousands of dollars in points on the table. Something to think about, David R.
