Quote from Amazon:

Despite our best efforts, a small number of the more than 4.7 million items in our catalog are mispriced. Rest assured, however, that we verify prices as part of our shipping procedures.

-If an item's correct price is lower than our stated price, we charge the lower amount and ship you the item.

-If an item's correct price is higher than our stated price, we will, at our discretion, either contact you for instructions before shipping or cancel your order and notify you of such cancellation.

所以要吵也沒用.
