Last September, Bleeding Cool pointed out that the Amazon US listing for the upcoming Spider-Verse Hardcover had glitched, down from $75 to $30. It's now at a more modest discount of $50.
Today it's Amazon UK's turn. The listing has the wrong standard price listed of £25.99 and the discounted price brings it down to £17.67 for a 640 page Marvel hardcover, to be published in May. With free shipping. This is below what stores will be able to buy this for at wholesale from their distributors – so canny UK stores might like to shift their order to Amazon instead,
At some point, this will change. But not right yet.
