It doesn't really matter how she's pricing it, the people that will buy it will buy it even at this cost.not gonna lie, her plans are pretty expensive, 36 US dollars for the full plan and only 2 posts per month in that plan, she is even charging more expensive than pornstars in fantia with regular posts. she should have started like Aichan did with plans like 1,100 yen and then upgrade to another more expensive.
And she's most likely charging this much because she will not sell that many plans.
