Want a quick $600? First Interstate Bank is offering a bonus of $300 for opening a checking account and another $300 for opening a savings account! Here's the deal: you need to use the promo code FALL25BONUS when you sign up. For the checking bonus, you'll need to set up at least three direct deposits of $500 or more within 90 days. The savings bonus requires you to deposit $10,000 within 30 days and keep it there for 90 days.

This is a sweet deal, especially if you're already in the market for a new bank account. Keep in mind that this offer is only available in CO, IA, ID, MN, MO, MT, ND, NE, OR, SD, WA, and WY, and you'll need to open the accounts by November 21, 2025. There's a small monthly fee for the checking account, but you can easily avoid it by setting up direct deposit or keeping a minimum balance of $250. Also, watch out for a $10 early account termination fee if you close the account within 90 days. Bank bonuses are considered income, so you'll have to pay taxes on the bonus amount, but hey, free money is free money!
