HP has been selling Palm phones through its recently created wireless central online sales portal since it went live a few weeks ago, and the company is looking to sweeten the deal on already free-on-contract AT&T Palm phones by giving a $50 gift card, reedeamable on HP.com, with the purchase of any new Pre or Pixi Plus.
