The 2025 McDonald’s Filet-O-Fish promotion is causing quite a stir among fast-food enthusiasts looking for a reasonably priced seafood option. This temporary deal is a welcome diversion in a world where drive-thru prices have been gradually rising. This $5 offer, which is only accessible via the McDonald’s app, comes with a Filet-O-Fish and medium fries.
Although McDonald‘s has a reputation for running clever promotions, the timing and accessibility of this most recent offer make it stand out. The offer, which is valid until March 23, 2025, comes right before Lent, when a lot of patrons are looking for menu items that feature fish. McDonald’s decision to focus more on value-driven meals is a smart strategic move that will appeal to customers as inflation drives up food prices.
| Feature | Details |
|---|---|
| Deal | Filet-O-Fish + Medium Fries for $5 |
| Availability | McDonald’s app (Exclusive) |
| Limit | 1 redemption per customer per week |
| Promotion Ends | March 23, 2025 |
| Other Burgers in the Deal | Big Mac, Quarter Pounder with Cheese, McChicken, McPlant |
In the constantly changing fast-food industry, competitive pricing is crucial. McDonald’s is aware that low prices increase traffic, and this app-only deal accomplishes two goals at once by providing value and boosting online interaction.
By making the Filet-O-Fish offer available only on the McDonald’s app, the business promotes more app downloads, more frequent orders, and enduring client loyalty. Given how mobile ordering is still dominating the fast-food sector and enabling brands to track consumer spending patterns, customize promotions, and improve service efficiency, this is an especially smart move.

Additionally, McDonald’s timed this promotion flawlessly. The Filet-O-Fish is still one of the most popular non-meat selections on any fast-food menu, and during Lent, many patrons choose fish over beef or chicken. This offer feels perfectly suited to seasonal eating habits, making it more than just another typical discount; it’s both relevant and irresistible.
The Filet-O-Fish has been a staple of McDonald’s menu for more than 60 years, despite its underappreciated status. Originally established in 1962 to serve Catholic patrons during Lent, it has since grown to become a mainstay of the fast-food industry.
What attracts and retains customers?
The Filet-O-Fish differs significantly from the other items on the McDonald’s menu. The Quarter Pounder and Big Mac have strong, beefy flavors, but the Filet-O-Fish has a softer, cozier flavor that is still very satisfying.
This is only the beginning of the Filet-O-Fish deal. As digital sales continue to rise annually, McDonald’s has placed a greater emphasis on promotions that are only available through the app.
Discounts aren’t the only reasons for the move to mobile ordering; customer data, tailored marketing, and operational effectiveness are also key factors. McDonald’s can customize promotions for each user by increasing app-based transactions, which will guarantee more frequent visits and higher total spending.
As McDonald’s continues to hone its digital-first strategy and reward devoted customers who interact through their mobile platform, expect more offers like this one in the future.
