Just wanted to give a heads up the Lowe's 20% off deal looks like it ends today, so stock up once again if you need to or intended to and never got around to doing so. Figure it can't hurt to grab 4 more 2pk's.
EDIT: just wanted to update this post, use coupon code "470000RRRR2997R" which gets you $10 off of orders $50 or more, so if you get 5 of these 2pks at 12.99 each, after the 20% off and the $10 off, my total at least in my area puts me at $44.90!
