Hunh, got it for $30, currently in "Shipping Soon" so can't cancel... Gonna e-mail their support.
Edit: Used chat support; support offered to refund the difference once shipping was complete.
Edit 2: Transcript if anyone needs it.
Initial Question: The item "animal crossing" is shipping soon but has just dropped to $26.59. Will I be credited the difference, or do I need to try to cancel this item immediately?
01:58 PM(GMT) Adriel(CSA): Hello [mwoody450], my name is Adriel.
01:59 PM(GMT) Adriel(CSA): I'd be glad to check what are the best options for you.
May I have the order number so I can check?
01:59 PM(GMT) [mwoody450]: Yes, one moment...

01:59 PM(GMT) Adriel(CSA): Thanks.
02:02 PM(GMT) Adriel(CSA): I've checked the order and I can no longer cancel the order since it has already entered the shipping process. It's currently being packed, labeled and ready to be shipped.
Here's what I can do for you.
I can personally set a follow up on this order and once the item ships out, I'll process a refund for the difference.
Does that work?

02:03 PM(GMT) [mwoody450]: Excellent, thank you!
02:03 PM(GMT) Adriel(CSA): You're most welcome.
I hope I was able to provide assistance and resolution regarding the concern.
Is there anything else I may help you with?

02:03 PM(GMT) [mwoody450]: Nope, that will do it. Thank you again, and have a good day.
02:04 PM(GMT) Adriel(CSA): You too.
Thank you for contacting Amazon. Have a great day!
