Thomas, you’re sort of correct. Since companies use sign-up bonuses as promotional tools, they’re not indefinite. Occasionally, they might even alter the bonus amount. In some instances, they may create a new page on their website for a fresh promotional sign-up bonus, rendering the old one obsolete. If you don’t spot the sign-up bonus information on the sign-up page, quickly search their website to check if there’s a new landing page for it or if it’s completely ended.
