Hi, yeah, I did check out the link but it looks like that might be the wrong form perhaps? Here's what it says:

"When is a buyer covered under the Amazon.com A-to-z Guarantee?

1. The buyer provided payment to the seller through Amazon Payments, but the seller failed to deliver the item.
2. The buyer received the item, but the item was materially different than as depicted in the seller's description. "

So it doesn't sound like that's where you get price matching or whatever? Did you just use one of those other options anyway?
