Could be an issue on the page itself.
I was looking at ordering a bigger item one time and they would not deliver it to my door. Choosing a different color (same model, still shipped from Amazon, same everything), and no issues. I ended up contacting them cause I really wanted the black vs the white, and the person said they have no idea why it was doing that, but I could place the order through them directly and get the color I wanted, delivered to my door.
It's the opposite of your problem, but still possible I guess.
