Please try and let us know what happens. I wonder what they would/could possibly do for this. Would they lay out money to buy one at the regular price for you?
Google Protection didn't help. Their response: "your order was cancelled due to a price listing error that you were notified of before your order was shipped, and you were, therefore, not charged for the order at all. In this case, Google Trusted Stores must abide by our merchant's policy and we will not be able to assist you further with this order issue."
