> **Short answer:** Price gaps between vendors usually reflect testing, sourcing, and shipping — not a deal. The cheapest vial is often the untested one.

## What you're actually paying for

Independent testing costs money. Domestic, reliable shipping costs money. A vendor that does neither can always undercut one that does.

## Why cheapest is a warning

When a price is far below everyone else, ask what got cut to get there. Usually it's the part you can't see on arrival — the testing.

## How to value-compare

Compare price against verifiable testing, not against price alone. Buying tested product once beats buying cheap product twice.
