So, I just did the exact same thing. My original order was placed on the 18th. The problem for me at least was they were fulfilled by amazon when I ordered them originally. I ordered a total of 4 and only received 3. The last one one got delayed so i contacted amazon about it and they told me it was "going to ship soon". Well, it didn't, so I got in touch with them again and the guy today said to just cancel. So, I told told him I could have done that last week instead of waiting for nothing. I asked them to compensate with an expedited shipping on my re-order, but since its not fulfilled by amazon anymore there is no telling what will happen. I've messaged Andy about it and currently awaiting his response. I'm not to worried about it but in the end amazon screwed up, so I expect them to make up for it but I'm not holding my breath.
