Since there are external dead lines Amazon has to meet with delivery carriers like USPS and UPS, they would need to work through the night to meet the next day’s deadline. Or perhaps increase capacity during certain shifts to meet those deadlines. I get the impression Amazon values exceeding expectations (happy customers) versus disappointing customers to save money in the short-term. This, I think, explains the motivation behind buyers liking FBA. Even though things might cost a few dollars more, but the great likelihood of receiving by the stated date is very comforting.
