Too funny not to post. Placed my order with McMaster Carr for supplies/parts. I ordered some 1/4" stainless flat washers. Most everything you order comes in packs of 100. Here is the washer I got for $6.36. I called them and they said this was correct. Lol.
I just sent them a email. I will post the reply when they reply. If you would like to look the washer up on their web site, Item#98189A200
So when somebody asks if I can include 4 bolts and 4 washers with their seat and I charge 25.00, you know why. LOL.
