Discount code raises already-insane shipping costs?

There's definitely some tomfoolery happening. As seen on another site this morning:

So the last parts I got from [another vendor] I had in the cart at year one, shipping was 28 bucks. I put in the discount code & saved $32, when I hit checkout they raised the shipping to $35. That pissed me off. I closed the window & went looking elsewhere.
Watch the numbers closely, folks. I just tried it and had similar results. Were this a YearOne exclusive part like a wiring harness, that'd generate a phone call on my part. Otherwise, I'd do what he did and just find a different vendor. Speaking of wiring harnesses, they've made many of the more-expensive examples "discount exempt" despite those having extraordinary markup (some more than 100%).

YO apparenty doesn't check this forum anymore, but if by chance they do: Nonsense like this is why you've gone from the 800lb gorilla in the Mopar restoration-parts world to just another cliff-bound lemming. The drain isn't getting bigger, you're just closer to it.
