But just because you can see a "price" for shipping. That doesn't mean that's what it actually costs the company.

It is literally my job to write the code that queries the carrier (UPS/FedRx/Speedy/Etc) and generates a label and receipt. 99% of our clients fudge the "cost" that the end customer can see. The end customer thinks it cost $20 to ship their package but the API returned $6 from UPS.

We also offer rating so that their website can "calculate" a rate of $20 externally and $6 behind the scenes.

I mean ultimately someone is paying the shipping but I don't see how it's bad, or good.
