Product Sourcing
Sourcing is about matching a product to a supplier who can repeat it.
Supplier signals
Years active, response rate and rating give a rough picture of reliability before you commit.
Volume tiers
Unit prices typically fall in steps as quantity rises; product pages show the tiers we were quoted.
Sampling first
For larger orders, buying a single unit and inspecting it first is the cheapest form of insurance.
