I've been having oddities with this too, Alex. It says my order went through and I talked to someone in their customer service chat and it seems fine. Yet the item is still in my shopping cart and I've gotten three emails saying that I have an item there and if I don't do anything with it, it'll be removed from my cart. Even though I ordered it. I fear if it does get removed from my cart, or if it's taken out automatically, that the perorder will be canceled. Last time I tried to snag one of these packs this happened and the item was in my cart even though I placed the order, removed it, and the order soon after failed. Perhaps a coincidence, I don't know.
Also they seem to have taken money out of my account for the item yet I've gotten no shipping confirmation email. So perhaps that's the issue you've been having. So if my order gets canceled after the item gets removed from my cart after so long I'm going to be very unhappy. I just want my accurate enough affordable pack, dammit. Hopefully it goes smoothly regardless but I'm keeping an eye on it.
Couple things- I experienced this weird shopping cart situation too. When I clicked on the link in my order confirmation email to check the status of my order, the first time I clicked it would take me to a shopping cart and when I navigated away from the page, it acted like I was placing a new order. When I went back to my email and clicked the SAME LINK a second time, it would navigate to a page that asked for my order number and zip code to look up my completed order. This happened several times and when I left the shopping cart with a pack in it, I got the "don't forget to buy" email. But they were separate "transactions." Maybe this happened to you too?
As for shipping, I saw posts here earlier today and kept checking my email (between doing other work-related things) and it finally came. My guess is that SpiritHalloween is finally moving through a shipment and emails are going out as the FedEx labels are being printed. So hopefully, you will get an email SOON!
Hope this helps.
