Sourcing and landed cost
Quoted in USD, landed, with the cost visible before you commit.
A unit price is not what an order costs. Freight, duty, handling and the timing all sit on top of it, and they are the part that tends to arrive later as a surprise.
We quote landed cost: what the gear costs delivered to you, on your account, with the terms stated. If something has a long lead time or comes from a single source, that is part of the quote rather than a footnote to it.
Where we can suggest an alternative that does the same job for less, we will say so.
