Got to say that I'm somewhat astounded at most of the responses on this thread. The OP asks about rip-offs. And what we get, instead, is a litany of things whose raw prices are high, or whose quality doesn't compare to the same food in another form, and so forth.
Overlooked in all of this is the concept of value-recieved. If I pay an excessive amount for a convenience product, but feel it was worthwhile because it saved me time, or was easier, or I just liked it, or any other reason, then the product was worth what I paid for it. Far as I'm concerned there was value recieved. If it were otherwise the salad bars in supermarkets wouldn't last twenty minutes.
So I'm curious as to how people define rip-off?
To me, a rip-off is something that doesn't deliver on its promise. The actual cost is irrelevant.
Here's an example. My mom, she should rest in peace, would go crazy if she knew what you and me pay for knives and cookware. For her, a pot was a pot was a pot. On the other hand, I willingly pay $60, $80, $125 for a pot, so long as it does the job it's supposed to in all respects.
A rip-off is when I pay that kind of money for an All-Clad pot which does not do what it's supposed to, and which the company doesn't back. It's not the $85 that's at issue, but that I paid $85 for a useless piece of cookware.
I know somebody who paid $1,200 for a hand-forged Japanese knife. Expensive? You betcha! But a rip-off? Not hardly. So long as the features and performance are there (and, apparently they are, cuz he loves the thing), then there was value recieved.
What's that you say? You would never pay 1,200 bucks for a knife? Your choice. Value, like beauty, is in the eye of the beholder.
To me, the biggest joke in the food industry is those Crockpot Classics. Everything you need to make a crockpot meal all in one frozen package.
Putting aside quality and nutritional issues, how long does it take to chop some meat and veggies and toss them in a slow cooker? To me, the very idea of such a product is the greatest marketing ploy since Eve convinced Adam that a snake did it. But when I expressed that opinion on another list, a member, rather indignantly, pointed out that the product let her spend ten more minutes with her grandchildren, and so was worthwhile.
In her eyes, there is value recieved.
