Heads up, deal hunters! There's a way to potentially snag an extra $100 on top of the ongoing 4% bonus when you sign up for something (the article doesn't specify what, but context implies some kind of investment or savings account). The trick is to use a referral link from a friend (or a generous internet stranger!).

Here's the catch: If you're using a referral link, you won't automatically get the 4% bonus. You need to manually enter the code BIGDEAL on the application summary page before you fund the account. Failing to do this means missing out on that sweet bonus!

Why should you care? Well, an extra $100 is an extra $100! Plus, the 4% bonus can significantly boost your returns, helping you reach your financial goals (and maybe fund that dream vacation!) faster. Don't leave free money on the table – follow these steps carefully!
