I used to have a PB&J maker...but one day, mom started telling me to make my own sandwiches.

*bah dum bum cymbal*
Pengwuino, you're never going to make it in marketing. You've missed the real cash cow here...the PB&J machine is a decent enough idea, but it would have to be something that sells in the range of $12.99 to $19.99 (maybe the regular price is $19.99, but the QVC price is $12.99), and that's not going to make you rich any time soon. But, the real money is in making the special peanut butter and jelly that people will have to buy to put in the PB&J maker. You'll have to sell a special, extra creamy peanut butter (it doesn't smoosh the bread when it's spread!), and jelly in a unique container that is the only thing that will fit your PB&J maker, and then you charge $5 for every 12 oz refill. See, now this doesn't seem excessively expensive to people yet, but then after they're hooked on it and don't know how they ever lived without a machine to make their PB&J for them, you make the refills only 10.9 oz (after a brief period when you sell a bonus size so people don't remember what the old size was), for the same price, and then when people get used to that, you advertise, "NEW" packaging, now with 10% more product, and sell the 12 oz again, but now for $7. And that's how you make your money after they're hooked on the product.
