Update: according to some of the comments, you can just talk to Newegg customer service and they will match the eBay price and give you the games. In that case a Citi credit card wouldn't be needed.
Here is what you need to do:
1. Buy it from Newegg using your Citi credit card
2. Submit Price Rewind Request Form with your Newegg receipt and screenshot of the eBay listing from the link below
3. Get your price difference refund from Citi! HOORAY!!
It worked for me. It took them only 3 business days to issue the refund.
