It was my first consultation, but it was a place where many acquaintances had successful results, so I just registered for a surgery date right away through a referral.
It probably varies by person, but it seems they take about 5–10% as a deposit, and maybe because the pricing is competitive, I didn’t feel it was extremely expensive.
I am a bit worried because it’s summer, but the place I visited was not very far from the station either (important), and I liked that they calmed my worries as much as possible.
