No idea how many competitors there are (Although treating it like the 15% is guaranteed indicates 'None,' notwithstanding the therefore-irrelevant talk about cutting the price to get competitive superiority later) or how many of them you can sell, or a ballpark market price, makes the whole thing meaningless. A DUmmie economic treatise meaningless?!? Yeah, I know, what surprise.
I once knew a guy who among other things sold buns to fast food restaurants, about 40 years ago in the town where I went to high school. One day he was chatting with me and my ne'er-do-well buds and decided to teach us an economics lesson. He told us he made 33% profit on an item every time he sold it but would go broke if he had to depend on it alone. He was talking about the buns, and explained that each one cost him $.02 each, and he got $.03 each for them from BK and other customers. He then noted that if that was all he had to rely on, he'd go bankrupt, because he couldn't move enough product to make a living from the existing demand he served to ever survive on it.
Profit margin alone is not enough information to make sound decisions...and as many have noted already, 15% is beyond the wildest dreams of vendors in most industries.
