Why do you say that? What dictate's that you should pay such an outlandish price for four bolts.

Sometimes you have to bypass the middle man & go directly to the source. An example is the ten feet of retract air line tubing that you get neatly rolled & packaged from Robart for six bucks at the LHS.
I did a little research and found the exact same tubing in fifty foot rolls for ten bucks a roll. Another example was locating Tygon tubing in fifty foot rolls for $25.00.

The hobby is expensive enough without paying outrageous prices for the trivial stuff
