How these prices are worked out
Every price is divided by the net weight of filament in the pack, not the shipping weight, so a single spool and a 10 kg bundle can be compared on the same scale. Multi-spool tier discounts and minimum-order coupon codes are applied at the quantity you pick, which is why the cheapest option changes as you buy more. Prices marked unconfirmed haven't been re-checked recently and are ranked below the rest. More on the method.
