I received the package safely, but there was a tidings that the package would be shipped on the following Fire day (12th) after I purchased it on the 7th, but the shipping notification was on the 13th.
I tried to cancel the order on Monday (18th), but they replied that they could not agree to cancel the order because it had already been shipped.
I received the notice of shipment on the 13th, but it was postmarked on the 21st, so I would have appreciated a Darkness rating, but I received the product.
