I used to work for a brick and mortar's on-line (website) Customer Service. There were certain zip codes that we wouldn't take orders from, mostly a few in NY and also a few in the Miami area since they had a very high rate of packages disappearing during the day.
All of our packages would start with UPS when they left the warehouse in the Midwest and then get passed off to the local post office for final delivery. It was like shooting fish in a barrel for thieves who only had to know approximately what time the mail was delivered in certain neighborhoods. We would ask the customer to check with neighbors, and wait a few days to see if it popped up. If not, we would replace the order at no charge and then file a claim.
We had multiple stolen packages each day from all over the country. We would have even more stolen close to Christmas and that would stink since we would send out via Overnight or Priority in some cases to get it there on time and somebody's Christmas would get ruined due to a stolen item.
After working there, I shop brick and mortar especially close to Christmas in order to insure the item is on time.
