Yes, in the US (Puerto Rico as well) this day is a major sale day. Everything is discounted in one-day-only sales. I keep away from the stores at this time of year except on less busy days because I’m not a healthy person and it takes a lot of effort for me to move through a crowd. As for holiday gifts, I never buy anything that the person wouldn’t truly want or need and I never ever buy things they can only take out and look at once a year. True gifts are always personal and from the heart.
