They get a flat fee of 50,000 yen (331.65 USD) for pitching it, with the hilarious clarification that Cover won't pay them more than once if they shill it in multiple streams. Confirmed by 2022 yab. Lots of girls don't even know they have merch sometimes. Mumei feels guilty about financially exploiting her fans love and just outright wont do it unless they specifically make her.
That unto itself basically disproves any dumb 'idols are rich' shillposts, if you think about it. Yes, they're millionaires and Cover tries to grease then with 300 bucks. Perfectly believable.
