Why this is different
Most price-check tools get this wrong on purpose.

Show one cash price. Pretend insurance doesn't exist.
Alethro
Compares insurance, discount, mail-order, and manufacturer side by side.
Insurance portals
Show a copay number with no context about deductibles.
Alethro
Shows what counts toward your deductible — and when costs drop.
Pharmacy apps
Push you to their preferred pharmacy regardless of price.
Alethro
Tells you the cheapest option, even if it's not us.
How it works
Three inputs. One honest answer. No upsells.
01
Tell us your drug, plan, and deductible.
Three short steps. Most people are done in under 30 seconds.
02
We compute against published rates and formularies.
Pulled from manufacturer pricing pages, NADAC, and carrier-published formularies. Sources cited per drug.
03
See four ways to pay — with the math.
Insurance, discount card, mail-order, manufacturer. Each shows what counts toward your deductible. We surface the lowest cost; you decide.
04
That’s it.
No account required. No upsells. Estimates only — verify with your pharmacy before filling.
