I published a book on the 22nd June, although I received the confirmation email, it took ages to actually appear on Amazon and now there is no pricing available on the American site, only on the UK one (sorry haven't checked all the EU ones). I didn't do anything different when publishing this one, is this just a glitch?
I am having the exact same problem. I published a short story about 3 am this morning and when I got up it was live and I had the e mail message. when I checked it said price unavailable and the uk has a price.
I have never had this problem before so wondering if Amazon is backlogged or something.
I re published it just a bit ago because I had forgotten to put tags in. Maybe that will jar it into displaying a price. Other than that all I can suggest is writing to customer service if you know where, I can't seem to find an address. I will wait and see now when it's live again if the price shows up. If not I will have to track down an address for customer service. Hope your price shows up soon.
