Heads up, Amex cardholders! It looks like American Express is sending out targeted offers to open a new Amex High Yield Savings Account with a bonus attached. The latest offers range from $300 to $500, with the bonus amount varying by person.

Here's the catch (as always): you'll need to deposit at least $25,000 of new money (meaning, not transferred from another Amex account) and hold it there for around 90 days to snag the bonus. The specific deposit deadline and hold period varies by offer, so read the fine print carefully! Also, these are targeted offers, so you'll need to check your email, Amex Offers in your account, or even just keep an eye out for a popup when you log into your Amex account.

Why does this matter to you? Well, if you've got some cash sitting around and you're not using it for immediate expenses, this is an easy way to earn a little extra. While $25,000 is a hefty chunk of change, the bonus plus the already decent interest rate on the Amex Savings account could make it worthwhile. Just remember to factor in the tax implications, as bank bonuses are considered taxable income. Keep an eye out for the offer and see if you're one of the lucky ones!
