I recently ordered a 2 bolt kit (GM Part number *******). This is a kit that contains two oil filter housing bolts. These guys cut open the packaging, removed one of the bolts, then scotch taped the bag back up to make it look like it only came with one. It is clearly printed on the bag that 2 bolts are included. When I contacted them, they said I would have to pay the same price again to get the other half of my order. What a scam.
