For those who still actually have Kmart near them, use the PDF KMART coupon to get $10 off, obviously it could be used for just about anything, but from another post they carry Mobil1 as well so... I have a free change coming up, so I'm just going to grab it for stocking. Beware, supposedly a manager may have to override to work since for some reason some places are not accepting the coupon.
