UPS and FedEx were swamped this year moving and delivering packages. I attribute the chaos to the uptick in online sales. This year, I did most of my shopping online with only one snafu. The backup only affected one gift from me, flowers, an order we canceled because UPS admitted to not having the capacity to deliver the flowers as promised. The delays didn't stop consumers from searching online and buying gifts for themselves and loved ones, even on Christmas Day. In fact, Christmas Day online sales rose 16.5%, compared with the year-ago day, per IBM's Digital Analytics Benchmark report.
