So I got an email back from Amazon. Here's what it says
I'm so sorry to hear an incorrect price was displayed for the SCIVATION Xtend Intra-Workout Catalyst and Zero Carb Isopure when you placed your order.
At any given time, despite our best efforts, a small number of the millions of items on our site may be mis-priced. Our sellers work very hard to accurately list their products, but on rare occasion a pricing error may occur. While an occasional error is bound to happen, we do require sellers to keep these to a minimum.
We track seller cancellations, and if we find a seller's rate of cancellation excessive or a seller's listing issues become problematic, rest assured, we will take appropriate action. Even though orders canceled by sellers no longer appear in Your Account, the option to contact the seller or leave feedback will become available three days after the order was canceled. Just click "Your Account" on the top right-hand side of the Amazon.com homepage. You can also use the link below:
http://www.amazon.com/your-account
Go to the Orders section and click "Leave Seller Feedback".
I can see you're upset, and I can assure you that I'm here to help and will do everything possible to resolve this.
If you're still interested in purchasing the SCIVATION Xtend Intra-Workout Catalyst and Zero Carb Isopure, you're welcome to place a new order (as long as it's SOLD AND SHIPPED BY AMAZON or at least FULFILLED BY AMAZON, not shipped by seller). For your convenience, I've provided the current listing for these items below:
SCIVATION Xtend Intra-Workout Catalyst www.amazon.com/gp/product/B005CH0FAG/
Zero Carb Isopure www.amazon.com/gp/product/B0003S5496/
Then, please write back with your new order number using the following link, and we'll definitely make sure to honor the price as an apology gesture and one-time exception to our standard policy
I hope this solution works for you. I look forward to assisting you again.
Best regards, Asriel C.
So I've place my new order and contacted support with my new order. Hopefully it all goes smoothly and I get charged my original price. I'll update when I get confirmation that Amazon has updated the cost of my new order with the amount of the old one.
