Confirming a genuinely one-time purchase, without unexpected auto-renewal, is worth thirty seconds before entering payment details.
Confirm whether any checkbox pre-selects a subscription option before you submit payment, since this formula's materials don't explicitly rule out a recurring charge on every package tier.
Contact customer service directly and get written confirmation of the billing terms before entering payment information, rather than assuming based on the displayed price alone.
