That is true for replacement interior parts, and specialty items like that.
Not as true for a lamp that has countless automotive and industrial uses.
Somebody had mentioned their FBO selling 4509 bulbs for $25. They are not
hoping to get your maintenace parts sales, they are wanting to sell to that
poor guy that is trying to get out of there at 10 at night and no where else
to buy a landing light. So, best advice, if you find a reasonable price,
stock up and keep a couple on hand.

I wonder if the markup was really at the retail end or just cumulative
along the line. Once the "airplane" pedigree is attached, everyone
appears
to have a license to steal in the name of "liability". Then again, the
"lottery" mentality of many might lead me in the same direction.

The problem all aviation parts/supply sellers face is that the aviation
market doesn't support much sales volume. So, to stay in business, those
retailers charge larger markups than many other retailers. The less stuff
we buy from aviation sources, the worse this low volume/high price spiral
becomes. It's a Catch-22..
