Solarity Credit Union might be offering an easy $100 bonus for opening a "Bonus Savings" account. The catch? You need to jump through a few hoops within 60 days of opening the account: sign up for eStatements, link the savings account to a Solarity checking account, and make at least 20 debit card purchases each month. If you manage that, the bonus should hit your account within 90 days.

This is potentially interesting because it looks like it might be available nationwide through a workaround (donating to the GoWest foundation). Usually, these deals are limited to specific states (in this case Washington), so the nationwide possibility is a big deal. There are no monthly fees and no early account termination fee, making it a pretty low-risk way to grab some extra cash.

The big unknowns are whether they do a hard or soft credit pull (soft is better!), whether they use ChexSystems (which tracks your bank account history), and if you can fund the account with a credit card (for potentially earning credit card rewards). Keep an eye on the comments section of the original article, as readers will likely share their experiences and data points!
