When you added it to your cart, it was probably offered from a different seller than it is now. If it was Amazon offering it initially they were probably giving a discount for a new contract or renewal. Always check who is selling the phone.

Either that or discounts were being offered for the holidays and they are no longer.

Hi ,

Last month when I visited amazon.com for HTC ONE X 32 GB the cost is around 499 $. Due to some credit card issues I didn't purchased and kept in shopping cart. But now its price increased for 100 $ more. Though it released one X+ and 8X and 8S why this sudden increase in price for One X. Not only this S3 and Galaxy Note II price also increased. Do you guys have any idea when this price can be down .
