Free One-Pound Lobster at Summer Shack on Your Birthday

Why it's worth it: A one-pound lobster at a casual seafood restaurant typically costs $25–$32. No purchase needed.

Dine-in guests get a one-pound lobster on their birthday, with no purchase required. Bring a valid ID showing your birth date, since the deal only applies on the day itself. Takeout doesn't qualify, so you'll need to eat at the restaurant. Check Summer Shack's site for participating locations and any signup requirement.
