Query: Penny pinching Porter Cable

I've been looking for a dust extraction adaptor and just found one but I don't trust that it will fit. It is located in the US and apparently costs about a dollar and a half. The first search I had the same as your fellow countrymen was for the screws that shurely should come with the Router Kit that locate the guide rods. Not supplied with the Kit I was told but got 30 back from Amazon who said these were not available through them. I looked on the Amazon site & bought 100 of these very necessary screws in Stainless for 11. Because these items cause frustration and annoyance to the buyer why on earth don't Porter Cable get their act together and supply these measly items with the Kit or is it the fact they are just too damn mean ?
