Filament deals, ranked by what they actually cost per kilo
A 40% discount on a £30 spool is worse value than a £12 spool at full price. Amazon shows you the discount; we show you the number that decides it — price per kilogram, across every spool we can find.
What filament actually costs right now: a typical PLA spool works out at £17.84 per kilogram, and the cheapest filament we track is £5.95/kg. Both are recalculated from live Amazon UK prices, with bundles counted at their total weight.
