What this Amazon deal is worth
LEGO Technic NASA Mars Rover Perseverance Building Toys STEM Model Kit is $79 at Amazon, down from the $99 Amazon had on the listing when our tracker picked it up — a 20% cut that keeps $20 in your pocket.
The average discount across the 1130 deals carrying a percentage on Ring In The Deals right now is 46%, so at 20% off this one is shallower than the typical drop in the feed — it beats 2% of everything else live today.
There are 264 Toys deals live at the moment, and measured in dollars saved this is the 87th biggest of them.
We posted it 20 days ago, and it comes off the site on October 3, 2026, 30 days after posting. Retailers change prices and stock without warning, so Amazon's own page is the final word — confirm the figure at checkout before you buy.

How we check: our tracker reads the retailer's own listing, records the price and the original price exactly as Amazon published them, and posts the deal without anyone retyping a figure. No discount percentage is shown unless both numbers came off that listing. More on how a deal gets on this page.
What we make of it
This model kit allows builders to recreate the NASA Mars Rover Perseverance, providing a fun and educational experience for older children and adults who enjoy intricate construction projects. It's an excellent way to learn about STEM concepts through play, however, the complexity of the build may be frustrating for younger kids or those new to LEGO Technic sets. Be sure to have a good supply of patience and time, as the assembly can be lengthy and detailed.
Why this is a good deal
It is shallower than the typical Toys discount
The median discount across the 264 Toys deals we have live is 41%. This one is 20%.
What you actually keep
$20. A percentage is a ratio and a saving is money — on a cheap item a huge percentage can be worth less than a modest cut on something expensive, so this is the number we would judge it on.
Reasons to think twice
we have only seen this product once, so we cannot tell you whether the original price is a genuine going rate or a list price that nobody pays; the discount is only a saving if you were going to buy the thing anyway.
