First up, I want to say that your point is clear, even without this correction, but…
That’s not how percentages work. To make things neat, let’s assume they’re now selling things at cost (they’re not, they’ll still be making a profit).
A 75% reduction in price like this means that they were previously making 300% profit.
facepalm
Yep, you’re completely right. I’ll wind my neck back in now…
