I have an idea! You can follow through on your post in the Xbox Live Marketplace thread!
You made a post with offers. I sent you several emails with a list of what I wanted and I got no reply. I sent a message asking when you're going to get the codes, where to send payment, etc... And again you don't respond whatsoever. If you're not planning on following through with your advertised deals, then please remove your post. It's frustrating as a serious buyer to want to make a purchase - only to be ignored by the seller.
