I have it on good authority from Diamond Book Distributors that the current state of Amazon.com — where most of the books in the Top 100 are now comics books, oversized graphic novels priced at $8.34 and $14.99 no matter what the original price (sometimes up to $125) — is a glitch.
And it’s being fixed.
In all likelihood if your order is being processed, then you’re getting those books at that price and someone will probably have to eat the difference. If not, expect to get a firm but polite email from Amazon explaining that you won’t be getting these books at the price you ordered them at — though you are welcome to purchase them at the usual discount rate.
At the moment of this writing, Amazon's bestseller list is still full of obscenely cheap funnybooks.
UPDATE: As of 1:34 pm, the prices are back to normal (in the sixty dollar range.) We'll see what Amazon does now.
