The real answer.

Prices are increased before Black Friday so they can create sales by bringing the prices back down. Some also create custom version of products for Black Friday like big box stores will have special TV’s with reduced feature at sale prices. People not realizing it’s a different product than they’ve seen at higher prices.

Jan/Feb can sometimes be decent as stores want to clear out old merch to make room for CES announced products and get rid of winter clothing to make room for next season.
