Yep, it seems the dealer cancelled the order even if yesterday I received a confirmation that the item is on stock.
Beware - my bank explained that since you have pressed Buy on amazon, you have given authorization for payment from your credit card linked to amazon, and the seller can take that off without shipping, and then amazon will refund you (basically they steal from amazon, and if you're unlucky, the seller might see your credit card info and misuse it - though I am not sure about the latter, since I haven't been selling on amazon).
