I got an email from Amazon that my deck has shipped. According to the tracking number I should receive the Quantum Tarot tomorrow.
In defense of Amazon I order a lot of things from them and I have had only one real problem, a package that "went missing." Their customer service responded in under 2 minutes and sent me a replacement package by overnight shipping, even though the merchandise was only 2 days late. It is true that they cancel pre-orders if the publishers/suppliers are 6 months late in getting the merchandise to them. I personally think this is more a problem with the publishers/suppliers. Even then, if you request it, they will match the pre-order price when they get it in. I do not hesitate to order from them if I am happy with the price they are selling something for.
