They promise delivery within 10 business days of the order being placed. Before you purchase your tickets the website will tell you the latest day they would be delivered. I just purchased some last minute tickets for Universal - they are scheduled to be delivered the day before we leave. I trust underground to get them there even earlier - not later. We ordered our WDW tickets well in advance and got them within the same week. I already got an email letting me know our Universal tickets have been shipped.
