It's best to sign up early! Some merchants send birthday rewards weeks in advance, while others send them right before your birthday. Signing up at least a month before your birthday gives you the best chance to receive the offers you're interested in. And remember: some offers don't require any signup at all! Check out the 'No Signups' category or filter.
Plan ahead! Sign up early for offers that need registration, and keep an eye on your inbox as your birthday approaches. On your actual birthday, focus on redeeming same-day-only deals, then use your birthday week or month to enjoy the rest. Each offer page lists how long it's valid, so you can have idea of how much time you have. Make sure to visit the site for every birthday to find new offers and confirm how to remain eligible for your favorite offers.
Many are, but not all. Some merchants offer 100% free gifts, while others provide discounts, complimentary freebies when you make a purchase, or gifts to loyal shoppers who have shopped with them before. The Birthday Freebies tries to note any conditions on each offer, so you have an idea of know what to expect before heading out.
Some merchants may ask for ID to confirm your birthday, especially for in-store offers that are redeemable without signup. Try to bring your ID when redeeming any offer, just in case!
Many are available nationwide, but some deals depend on where the merchant operates. Each offer page includes a handy Google Maps link so you can quickly find the closest participating spot near you.
