iRobot Roomba 860 - $405 (before tax) at Target.com with Store Pickup Promo
Deal DetailsLast Edited by TattyBear June 13, 2016 at 08:49 AM
Comes out to be $404.99 before tax (if applicable for your state).
Can get a bit more discount if you do cashback and/or have a Red card.
Alternatively, if you have a Lowe's moving 10% coupon, roughly the same deal ($405 after sale and 10% moving coupon) but can get it shipped rather than store pickup.
