The cheapest way to buy your whole filament list

List what you need. FilaNexus tries every mix of stores, with bulk discounts, coupon codes and each store's free-shipping minimum included, and shows the cheapest total. Pick a finish or color and it only looks at spools that really come in it.

How it works: every line is priced with the same per-kilogram maths as the rest of FilaNexus (net filament weight, bulk tiers and coupon codes at the quantity you buy). Colors and finishes come from each store's own variant list, re-read daily, so you only see combinations that exist. Shipping uses each store's published rule for the contiguous US. Where a store doesn't publish its shipping fee, we say so instead of guessing. Sales tax isn't included, and discounts are worked out per line, so a store-wide code that only unlocks across several lines may save you a little more at checkout. How we check prices.
