Way to un-hijack the thread. Bravo!
How do I put this without seeming to be a smartarse?
Americans, I like you guys. I do. But seeing people write a list like…
GUNS
TOILET PAPER
…is just surreal.
This is NOT an anti-gun post. Reading that stuff actually made me smile.
Well, you see, they’re both on the same aisle at the Wal-Mart, just across from the Bibles, Coca-Cola and Toby Keith CDs. That’s why we tend to think of them together. 
Brakes
Bourbon
Housing (I mean spending the money to be somewhere pleasant)
Pet food
Pocket knives and multi-tools (I like Gerber brand)
Scotch tape
All other kinds of tape
House paint
pr0n is definitely a product where you get what you pay for.
I second (or third?) tools.
Running shoes. Pay it now or pay more to the doctor later.
401(k) contributions.
pr0n? I’ve never paid for it and can see pretty much whatever I want, whenever I want.
backpacking gear. The last thing you want is your boots falling apart, stove not working, tent leaking, etc. A lot of people also buy designer equipment for when they are going out in the wild. That stuff may be great for popping over to wal-mart, but not so great if a blizzard suddenly closes in.
Sushi - the cheap stuff is revolting.
I gotta disagree here. My husband was of the same mindset, and went to Notre Dame, University of Michigan and Northwestern for his various degrees. Now he’s kicking himself because he’s ABD* and we have an obscene amount of student debt - so much that we simply cannot get a mortgage in an area we need to live to work - and no potential employer gives a rat’s ass what names are on his CV. They just want to know what he’s published and how recently. Perhaps it’s different outside academia - but I’d expect universities to be the snobbiest about which university you attended, you know?
*All But Dissertation - he completed the coursework for his Ph.D. years ago but it still working on the damn dissertation to get the actual degree.
Chicken - free range and organic, incomparable to the usual farmed rubbish.
(Minimum £10 each ($20) for a small bird, but worth every penny.)
When you hear the SHK-SHK of a shotgun in the dark, toilet paper is a must-have item.
Parachutes.
But you’ll have more more fun with the prostitute! 
Of course you will. With a lawyer, the idea is that the more you pay them, the harder they will screw someone else on your behalf. With a prostitute, the pleasure’s all yours.
That’s not always true. Sometimes you pay the lawyer to keep someone else from screwing you. When would you pay a prostitute to cockblock you?
Eggs. I’m not particularly sensitive to the plight of battery hens, but I do object when the eggs they produce turn out to be more grey than yellow. And I’m a cheapskate on nearly everything else (except bin bags and toilet paper).
Penile implants.
I’m just guessin’.
Razor blades.
Clothes: not expensive, but not the cheapest generally. For something you plan to keep, go with something decent like Lands’ End, it costs twice as much as Target but lasts more than twice as long and feels better. Lands’ End has overstock though which is even as cheap as stuff from discount stores.
Chocolate: Again nothing exotic or expensive, but Lindt Excellence (especially the dark) is miles better than standard Hershey’s. Hersey does have a premium line now, which is decent but not quite as good as Lindt.
Loudspeakers: Same deal again. A few hundred bucks will get you an amazing pair of bookshelf speakers these days, from PSB, Paradigm, NHT or others. They’re the most important, you can go cheaper on electronics.
