Fake monks: In some Australian cities fake monks walk the streets asking for donations. They don’t actually say anything though, instead they just put a gold token in your hand and show you a list of people who have already donated.

Decoy pricing: There are three phone contracts to choose from. The 1st phone contract is basic and cheap. The 2nd phone contract is expensive but lacks features compared to the 3rd contract. The 3rd phone contract is about the same price as the 2nd contract but has those extra features. You feel like you’re getting a deal because you don’t have to pay extra for those extra features.

Software that speeds up your computer: It’s usually so loaded with spyware that your computer will slow down.

Any "business" where you have to sell stuff to your friends AKA Pyramid/Multilevel Marketing: If you do manage to make any money off of it, then you’re the one doing the scamming. And your friends will hate you.

Psychic Mediums: They’re called “Mediums” because what they do is neither rare or well done. And yes, that was a serious joke.

Natural herb and supplement shops: If anyone ever tries to sell you “medical grade” cinnamon…leave.

Star Registries: Do you really think that you get to name a star for $50? Maybe you can look into the List25 “star registry”. We’ll let you name a star for $50 too! (that was another joke)

Unlimited data cell phone plans: Nothing is unlimited. Nothing.

Antivirus software: It’s usually a bigger virus than the actual virus.

Checkout donations: You’re just helping the grocery store/restaurant/etc with their PR. They’re the ones with all the money and goods. Why do you need to get in the middle of it?

Homeopathy: The only thing it is guaranteed to cure is your dehydration.

Oxygenated Water: Please explain more about how your stomach is involved in respiration…

6 minute abs: No way. It’s going to take at least 7 minutes.

$100 HDMI cables: The $5 ones are just as good.

The biggest download button on the page: The bigger and more colorful the button…they more likely you are to land on a not-safe-for-work webpage.

Diamonds: They really aren’t that rare, or even chemically remarkable. Some clever marketing campaigns back in the day, however, managed to convince people they should spend 3 months worth of their income on a diamond engagement ring. Geniuses.

Timeshares: You’re absolutely positive that you will come back to this exact same spot for vacation next year? And the year after that? You won’t want to go anywhere else?

Anything free: If you’re not paying for it then you’re not the consumer. You’re the product.

Lifelock: As the CEO himself can explain, nobody can protect you from hackers completely. They just can’t.

Bottled Water: You’re paying for plastic.

Brand name painkillers: Generics and store brands are chemically indistinguishable. But whatever makes you feel better…

Private, for-profit colleges: You can definitely get that education somewhere else for cheaper. And if you can’t, then you most likely don’t need it.

"Free" financial advisors: If they’re not charging you, they’re working for commission.

Phone calls for donations to the local police: If a charity calls you, it’s most likely a scam and the intended recipients will only receive a small percentage at best. You already support the police anyway…with your taxes.

Travel Insurance: If something actually does happen…well, good luck getting the insurance company to pay up.
