As of March 1, the DIRECTV rebates for existing customers have ended, but prices on HD TiVos are down by about $100. New DTV customers will still be able to get rebates – details from DIRECTV are still coming.
For standalone TiVos, and DVD/TiVo combos, TiVo has extended the $150 rebate for another two months. More details and links are on our rebates page.
