What matters for this question
- Calculate unit cost from a current pack price and verified count. A larger pack can have a lower per-head price yet cost more upfront.
- Exclude any head that has no documented fit for your handle before comparing prices. The site does not publish unverified marketplace prices.
How to apply it
A cheaper pack is useful only if the refill is the correct one. Use the calculator with a current price and pack count, then compare annual consumption cost with the whole packs you would actually buy. Do not use a generic compatible listing when exact model support is absent.
