I am writing this with no numbers at hand, which Readalot obviously has, to come up with this figure, so I am just talking out of my backside.
But I agree, on first impression, even "just " 5$ more x vial seems like a lot.
Is the source executing all the tests in the first place? But also, like Sampei says, they would be able to absorb the cost x vial, to a good extent.
They have big margins on this stuff, I believe.
Of course, not everyone is a massive operation like Qsc, where that can easily happen.
Domestic sources, however, are still moving big quantities of products.
I am in the camp that doesn't mind paying more.
But what is fair, also, and not be taken for a ride with this used as an excuse to overcharge people.
