I saw the Tricklestar multi-sensing outlet, model 188LV-US-7XX-MS, for $23 after an instant rebate, at
Its only for National Grid customers. Looks to be the higher end model. Found it on Amazon for as low as $29.99 with third party vendors, and it was a whopping $79.99 at Home Depot.
I didn't see any tax or S/H, but I have finished my purchase yet due to issues with verification for the rebate.
