How does the Doppler rental billing system work?
By placing an order for a First Beats Doppler, you authorise us to debit your credit card with the first month’s rental fee, plus a non-refundable delivery and return fee. This first payment will be charged on the date the First Beats Doppler is shipped to you. Then each month on that date, your card will be charged until the unit is returned or the purchase price of the Doppler is paid in full.
