Order #323965:
During the ordering process, I entered a 30% discount code ("30offshipping" found on line).
A pop up at that point stated that it was applied.
When I clicked 'calculate shipping': I got a pop up stating that the shipping cost would be calculated during the checkout process.
My order was processed without my knowing if the 30% discount code for shipping was applied...
Therefore this point it looks like I was overcharged.
