NASA Federal Credit Union is offering a sweet $300 bonus for opening a new Premier eChecking account. To snag the bonus, you'll need to set up a recurring direct deposit of at least $500 per month for three months and make at least 15 debit card purchases each month for three months--all within 120 days of opening the account. Make sure those direct deposits are legit ACH transfers from your employer, payroll provider, or benefits payer, as they're cracking down on what qualifies. Why does this matter to you? Well, $300 is a decent chunk of change for a little effort. Just be aware that this particular checking account comes with a $10 monthly fee that apparently cannot be waived. Also, keep in mind that the bonus will be credited to your savings account about 5 months after opening the account, and you'll be responsible for taxes on it since the IRS sees it as interest income. If you're looking to boost your travel fund with some easy cash and don't mind switching up your direct deposit for a few months, this could be a worthwhile offer!
