Amazon Prime Big Deal Days: Exclusive Prusa 3D Printing Offers Revealed
Amazon is back with another extravaganza, with official Prusa Research gear a headline feature in the Prime member-exclusive sale. Casting our net wider, we've found other stores that are cashing in on the action, too.
It’s a sale before the big sale to get you warmed up. Are you warm yet?
This month’s Prime Big Deal Days takes place from October 7-8, 2025, with 3D printing deals in particular curiously headlined by Prusa Research, which has a large range of its top products on offer, including the Core One 3D printing and Prusament filament. Amazon isn’t the first place you’d expect to find hardware from Prusa, so to see such a prominent batch of deals from the brand isn’t a bad thing.
Those well-versed in the shopping bonanza Amazon calls Prime Day (Prime Big Deal Days) can scoot a couple of paragraphs down for the deal details. Everyone else, pay attention.
Amazon Prime Day is a limited-time shopping event, where the everything-store Amazon puts on additional sales for paid-up members of its Prime subscription. The deal also applies to those in the free trial period of their subscription, so given that all plans start with a 30-day free trial, there’s really very little reason not to take a look and subscribe.
So far, so simple. And it is. Some deals last throughout the Prime Day event, while others are fleeting “lightning deals” – so it can pay to pay attention to what’s coming up.
Such is the magnitude of the event, other stores bank on the interest and time their own “Prime Day” or other sales to coincide. Below, we’ve picked out the stores and eye-catching deals we think you should know.

Shop Savvy
Just because a price appears to have dropped during a sale doesn’t mean that it is necessarily a good deal. Take the time to check price histories where you can.
There are a number of tools to help you do this, some that even we at All3DP use to keep tabs on prices and check whether a deal is, in fact, a deal.
Keepa is a tried and true service for tracking specific product listings at Amazon. All you need is the product ID–the first string of characters after the product item name in an Amazon product URL.
https://www.amazon.com/Fermerry-Silicone-Electrical-Cables-Stranded/dp/B089D2B6T6/
Searching the ID in Keepa will bring up a set of controls for tracking a price. Here, you can set thresholds at which to be notified, plus view the price history as far back as the product has been listed.
Alternatively, if you’re not keen on digging into the details too deeply and just need a quick indication, keeping the Microsoft Edge browser handy for shopping is another option. It has built-in shopping tools that will, in many cases, give you the immediate price history of a product you’re looking at. Better still, there’s a coupon-checking functionality that can automatically test out publicly known coupons for the store you’re on, potentially saving you a few bucks at no extra effort on your part.
Of course, the downside is keeping a browser around for the explicit purpose of shopping, but the possibility of not sleepwalking into a bad deal and maybe even saving a little more than you expect is a strong argument.
