Hurry: Five Guys Unleashes 4-Day BOGO Burger Deal—Score a Free Burger Before It’s Gone

Burgers lovers, set an alarm: Five Guys has quietly dropped a four-day “After Party” Buy-One-Get-One (BOGO) burger deal that runs from Saturday, March 9 through Tuesday, March 12. To claim it, open the Five Guys mobile app or website, add two qualifying burgers to your cart, and enter promo code FGAFTERPARTY at checkout. The second sandwich’s price will zero out automatically, effectively giving you a free burger for every one you buy, while supplies last. Why a second BOGO so soon? The chain’s one-day 40th-anniversary giveaway on February 17—unlocked with code 40FGBDAY—was so popular that many stores sold out early, sparking social-media frustration. This “After Party” is Five Guys’ do-over, spreading the offer across four days and limiting it to digital orders to ease in-store bottlenecks. How to redeem the Five Guys BOGO: • Download or open the Five Guys app (or use FiveGuys.com) and sign in. • Select any standard or cheeseburger; add a second to the same order. • At the payment screen, type FGAFTERPARTY in the promo-code field. • Place the order for pickup or delivery at participating U.S. locations. Fine print worth noting: the deal excludes custom patties (like veggie or grilled-cheese “burgers”), cannot be stacked with other offers, and is limited to one redemption per account per day. Because inventory is first-come, first-served, the earlier you order, the better your odds of scoring the freebie. Why this matters for fast-food fans With inflation still pressuring dining budgets, value-driven promotions from premium players such as Five Guys are rare—and they drive huge traffic spikes online. Searches for terms like “Five Guys BOGO,” “Five Guys promo code,” and “free Five Guys burger” spiked as soon as the code leaked, signaling high consumer intent. That makes this After Party a wallet-friendly chance to sample the brand’s fresh-griddled patties and famously large fries without paying full freight. Can it sell out again? Possibly. Five Guys cooks everything to order in-house, so individual stores can hit inventory caps quickly when demand surges. To avoid missing out, place a mobile order early in the day, consider less-busy locations, and keep a backup plan—fans on TikTok suggest saving your favorite order in the app for one-tap reordering when the code refreshes at midnight. Bottom line: From March 9–12 only, the Five Guys BOGO code FGAFTERPARTY is the fastest route to a free burger. Grab a friend—or keep both patties for yourself—before the After Party ends.
