To those considering making a payment

I'll just state the facts

Standard plan: 50% OFF at ¥772/month, ordered with a 1-year billing cycle = ¥9,264/year

Credit card charge: ¥12,539 (136% of displayed price)

I confirmed with customer service: "Isn't this calculation wrong?"

Customer service response: " The Japanese yen price displayed on the shop page (¥9,264) may be inaccurate; the payment screen amount (¥12,539) is correct."

This is a fact.
