Saw this Silk PLA listed at less than half the price of the store's other filaments. I personally ordered 8kg 3 days ago not knowing when/whether they would arrive but they arrived today! Make sure to choose "Ships from: Australia"
The same store has more filament listings but for much higher prices and without free shipping, not sure why this one is the cheapest but whatever :)
Combine with aliexpress coupons if you can get them to work
