We often have orders we want to fill on Fridays but that will ship on Monday. We do this so we are ahead for Mondays orders BUT also so the customer gets a notification that the order has been filled and will ship on Monday.
ShipSurance prevents this with their current 48hr policy. The result is that we have to hold these orders until Monday, not only making our workload higher but also delaying notification to the often impatient customers.
A 72hr grace period would fix this issue for companies that are not open on the weekends.
