The Ninja DG551 Foodi Smart XL 6-in-1 Indoor Grill with Air Fry goes on sale on Amazon, but deals come and go fast. Set your target price below and get an email the moment Amazon drops below it. No accounts, no fees, no browser extensions required.
The Ninja DG551 Foodi Smart XL is one of the most feature-rich indoor grills on Amazon, and it is also one of the most frequently discounted Ninja appliances during major sale events. The challenge is that Ninja DG551 sales on Amazon are brief and unannounced. Our free Amazon price drop tracker monitors the listing around the clock and emails you the instant it hits your target, so you can stop refreshing the page and start saving.

The Ninja DG551 is Ninja's flagship indoor smart grill and air fryer combo. Its defining feature is the built-in Smart Cook System: a probe thermometer that monitors internal food temperature in real time and automatically shuts the grill off the moment your food reaches your chosen doneness level, from rare to well done. That means no more cutting into steaks to check, no overcooked chicken, and no hovering over the appliance while it works.
Key features of the Ninja DG551 include:
The DG551 is the larger, smarter successor to earlier Ninja indoor grill models, adding the smart thermometer system and a bigger cooking capacity. It is well suited to households that grill frequently and want the versatility of an air fryer in the same footprint.
The most reliable Ninja DG551 deals appear during major Amazon sale events. Ninja indoor grill Black Friday sales consistently produce the year's deepest discounts on this model. Amazon Prime Day in July is another strong window, as is Cyber Monday. Outside of these events, Ninja occasionally applies coupon clips directly on Amazon listings, which can produce meaningful savings without waiting for a sale season.
The tricky part is that even during major events, the discount window can be as short as 24 to 48 hours. If you are checking Amazon manually, it is easy to miss entirely. A price alert removes that risk: you will be notified within minutes of any price change, whether it is a Black Friday promotion or a quieter mid-year markdown. Before the next sale season, our guide on spotting fake Black Friday discounts is worth reading so you can tell a genuine deal from a manufactured one.
Setting a realistic target price is key to getting a useful, actionable alert. Set it too low and you may wait through several sale seasons for a price that never materializes. Set it too close to the regular price and you will be alerted for a discount that barely feels worth acting on.

Amazon adjusts prices constantly and algorithmically. For indoor grills and kitchen appliances like the Ninja DG551, prices can shift in response to competitor pricing, seasonal demand, inventory levels, and promotional windows, none of which follow a publicly announced schedule. A meaningful discount on a product in this price range can appear and disappear within a single day. Setting a price alert removes timing entirely from the equation, because you will be notified the moment the drop happens regardless of when it occurs.
This Ninja DG551 price alert is ideal for:
It is designed for people who already know what they want and just need to know when the price is right. A price alert removes the timing guesswork entirely. For tracking other kitchen and home appliances, our product-specific alerts hub covers a wide range of popular Amazon products.
