They are expensive, but they help keep us healthy and alive a lot longer than without them. All that research costs money, too. How much is your health or an extra ten years of life worth to you?
Taxes
Every time I look at my pay stub, I weep over the thousands of dollars that are going to waste in the hands of bureaucrats.
Wedding
Three grand for a photographer? You’ve got to be kidding me. Outrageous! Then we found out his was the best price around.
New Car
Twenty-five grand for a brand new car? No thanks, I’ll drive a three-year old car and save $16,000 dollars.
Books
I buy used books almost exclusively.
Hiking and Climbing gear
The yuppies and young hipsters have ruined it for those of us who actually use the gear for it’s intended purpose. Sure you folks want to look trendy in your down-filled, expedition-weight shell, but my life might actually depends on them.
Legal advice
The list of minute charges is infuriating. You’re gonna charge me for leaving a message at my office? No thanks. Hello EZ Do-It-Yourself legal forms 
Music, Videos
I can’t remember the last time I bought a CD, DVD, or VHS tape for myself. I just can’t justify $20 or $20 for a film and $15 for an album. I know all about distribution. It’s just an unnecessarily top-heavy industry.
Hotel Rooms
Whew. I’d rather stay in my tent for the quality of service you get at your average hotel.
Milk and Orange Juice
Thank you Dairy Compact. Whats the deal with OJ? $3 for 1.5L?
Chinese Food
It just seems overpriced. It sure is tasty, though!
Airfare
Unless you plan months in advance, a cross-country round-trip fare can empty your bank account.
Paint/Lumber
I’ve never gotten over the cost of paint. or paint brushes!
Cable TV
I just priced some of those digital tv packages. Ouch! Oh sure, digital cable is all the rage, but they can’t find a way to offer a la carte packages. I watch a total of about 6 channels. Can’t you come up with a price structure for that?
Furniture
Mattresses, couches, dressers, et cetera. I can’t believe the prices being demanded for particle board.
