Deal Details
UPDATED: Best Buy is sold out, but the price directly from Polymaker is even better.

Polymaker [polymaker.com] has the Polymaker PolyDryer filament drying and storage solution on sale for only $51.99 after 35% ($28) discount (add to cart to see discount; use coupon code RESTOCKDAY if the discount isn't applied automatically). This is almost never on sale, and I've never seen it this low.



Many people buy these just for the dryer when converting their Bambu AMS into a Python AMS [makerworld.com], since it's no longer available separately, but it's also a very nice setup on its own.

About This Item
Polymaker PolyDryer is an all-in-one filament drying and storage solution designed to improve print quality by removing moisture from hygroscopic materials like Nylon, PETG, TPU, and even PLA. Moisture can cause issues such as stringing, bubbling, and weak layer adhesion—PolyDryer eliminates these by restoring your filament to optimal condition before or during printing. Featuring a preset temperature control, a spacious drying chamber, and compatibility with standard 1kg spools, it's an essential tool for makers who demand consistency and performance. With its modular design, PolyDryer can convert itself to a perfectly sealed filament storage unit after drying, keeping your prints smooth, strong, and reliable.

Features
  • Modular design
  • Removes moisture with active heating and circulation
  • Ideal for hygroscopic materials like Nylon, PETG, TPU, and PC
  • Improves print consistency and mechanical performance
  • Easy to use, with clear interface and quiet operation

Nice find OP.
I wonder if this would qualify for the $25 Polymaker coupon. If anyone bought it, and wants to upload their receipt. Please let me know Smilie.

If not, you can use that deal to get the $25 coupon and buy it directly from Polymaker for ~$26

I did end up doing that. I guess I'll see if the deal on this ends before I get my coupon from Polymaker

I went for the bundle as well. Prices are similar or higher on eBay*, even used (not that many people are selling these used, probably because they're too useful to get rid of). This should help with all the PETG I have.

*-(one eBay listing shows $43 after shipping but when you click on it it's just the box; not the dryer)
