No, that’s Black Friday. Most sales are fake, I figure theres 4 routes those sales go:

1. They jack up the regular price a month before and just lie saying the normal price is a “sale”.
2. Its an actual sale, but after the sale price will increase significantly.
3. Its the sale of an inferior product, most often seen with TVs and electronic.
4. It a real sale, often done by smaller entities pressured into taking a loss for the day hoping to either clear dead stock or get their product into more hands.
