The price is for 1 startmani (1 download - 1 startmani).
To make a purchase, you need to send a "unique code" to confirm the payment, in the chat you send a link to the infostart page (what you want to download) and an email address (where you need to send the downloaded file).
I reply to messages, but not immediately (either on the same day or after 2-3 days).
