Polymaker’s wild Restock Day sale is also live, knocking a blanket 35% off sitewide - no coupon code necessary. On top of that, the manufacturer is offering free shipping and 5% cashback on orders.
Napkin math tells me you'd be looking at savings of over $70 on ten spools of Panchroma Matte PLA, or over $100 off a 3 kg spool of Fiberon PPS-CF10, for example. If you were planning to stock up on filament anytime soon, this is the time, and Polymaker is the place. Until October 10, that is. That’s when the sale ends.
