This is a great idea. I have seen this kind of process used in clay crafting.
However, I think it is too expensive. And if you look on the Youtube video she makes a comment that maybe the price will go down if someone like Michaels picks it up. She then mentions that initial upstart costs are so high. It sounds like she is trying to recoup her start up costs by a deadline of April 8th. And then it will go up even higher?
I personally think she has priced this product out of the general market, because the current "introductory" price it is still too high. While this may appeal to those that make a high volume of cake balls, how many are those anyway compared to the general population?
I know from taking Economics in college that there is a formula she could do to predict how many sales and at which price point will give the best return. It doesn't sound to me like she did this, but instead she fulfilled a minimum manufacturing order and then divided the cost of that by how many she needed to order to get to her price point. I wonder if instead she took a bit of a loss and wrote that off if she would then actually have more sales and make her money and then some in the long run. That is a question that a marketing or econ expert could help her determine.
I don't blame her for wanting to recoup cost, but I believe the price point is going to turn some potential customers away. And I am one of them. I guess I will have to continue to resort to the by hand method. Or check out the meatball magic one at least.
ETA: After reading the verbage again I think she is trying to get a minimum manufacturing order by using the revenue from pre orders, or at least get a commitment by having the $1 deposit so she knows she will at least sell of the initial order. This is smart on her part because I have heard of people who order a run of tons of stuff and then it sits in a storage bin unused. So maybe if one expresses an interest at least she will be able to gauge how the market will work for this. So even if you don't like the price point, it might be worth it to let her know you have an interest. This may help her determine if she wants to go forward or not.
