It didn't take long for the Sprint HTC 8XT to be on the market before we started seeing penny sales. Amazon.com may be the first and is offering the 8XT for only a penny for new Sprint accounts. You've got the obligatory contract requirements but a penny isn't a bad deal at all.
Looking to upgrade? Then the 8XT will cost you $79.99 and to buy the HTC 8XT outright (without contractual strings) it'll cost you $429.99. There are separate pricing for those on Sprint's Family plan ($29.99-$79.99) and shipping is noted as "usually ships within 2-5 weeks".
Still... not a bad deal if you're in the market for a Sprint Windows Phone.
