The guarantee runs on a calendar month cycle — the 1st through the last day of the month, regardless of when you subscribed mid-month. At month end, the site automatically calculates your net profit/loss across all picks for that period. If you finish in profit, no refund is due. If you finish at a net loss, we process a refund of the net amount we received after credit card processing fees — approximately $87.80 per $100 paid — within 5 business days. You will be notified by email when the calculation runs and if a refund is being issued.
