HTC has launched an online store for the U.S. that allows purchasing of accessories and devices straight from them. The site has a filtering system that help narrow the results down by carrier (Sprint, Verizon, AT&T, and T-Mobile) and by type of plan (Individual, Family, Upgrade, or Pre-Paid).
You can access the site by going here. As of right now, HTC is offering free shipping for those who buy a phone with a plan, or at least $50 of accessories and ships to an address in the USA.
