Are you by any chance on a discounted plan? I had the same price a week ago.
I had to almost raise hell on the phone though to get that price, as I ordered it RIGHT when it came out and that price wasn't live yet. A very helpful rep was finally able to give me a credit, but then when I got transferred to technical support to get it replaced for pixel issues they wound up taking off the credit, as they could just charge me the cheaper price for the phone on the replacement they sent me.
