Did DigiKey lay off a bunch of employees? Now their web site says "Due to high order volume, orders may require up to 4 additional business days to process".
Since this has been going on for some time now, and apparently getting worse, it reminds me of how every company's voicemail says "we are experiencing higher than usual call volumes", when what is really happening is "we are experiencing lower than usual staffing, because management decided to cut costs by laying off employees".
