Black Friday

Sorry if this has been asked but I couldn't see it in recent days' posts. Just want to understand timing of deals so I don't feel stupid if deals are meaningfully better after Thanksgiving. I know no one will tell me with specificity what to expect next week, but I’d like to be able to make an educated guess.

  1. In last few years, were deals on the Friday after Thanksgiving materially different from those the week before?
  2. In prior years, when did Verizon releae deals labeled as "Black Friray" - was it actually on that Friday or a few days prior?
  3. Does VZW follow a set schedule for updating deals (day of week, first of the month, etc.)?
