If we have Black Friday after Thanksgiving where everything goes on sale. Does that mean April 5 is Orange Saturday where everything gets more expensive.

Every day is Orange Saturday.

No, that's Black Friday. Most sales are fake, I figure there are 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 electronics that the insides are easily swaped for cheaper parts.
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.
