This deal has ended.
Abt Electronics' $15 off coupon code is now expired (and with it the $19 deal of weeks past) but they are still in the competition for lowest 40-hour TiVo price at $34 with free shipping and no sales tax after the ubiquitous $150 rebate. The other option is CompUSA, where it is $19.99 but sales tax is charged on the $170 before-rebate price, effectively rendering the price difference moot. Their shipping is also free. The CompUSA price is valid through Saturday; Abt is ongoing.
