Black Friday as a Price Discrimination Scheme?

[I'm between classes, so as with the other posts today I don't have time to say much, but I suppose -- or at least hope -- that "echo mode" is better than not posting anything at all.]

I fully agree that price discrimination schemes are far more prevalent than people realize (some are disguised as two-part pricing schemes, e.g. cell phone contracts where there is a fixed amount for usage up to some point, and then high fees for anyone who goes beyond the fixed allocation is way for producers to extract surplus from consumers):

Price Discrimination Explains Everything, by Arnold Kling: In my high school economics class, my students asked me to explain why there are sales on "Black Friday." The class period was over, so I only had time to blurt out "price discrimination" without getting into an explanation of what it is and why it explains sales.
I think that price discrimination really deserves a lot more attention than it gets in the economics curriculum. A lot of "economic naturalist" sorts of questions are correctly answered by appealing to the concept of price discrimination. I think it explains airline pricing, credit card pricing, cable TV pricing, cell phone pricing, movie popcorn pricing, etc.
Suppose that a new video game console comes out. BZ likes video games, but he is only willing to pay about $200 for the console. JS lives for video games, and he would pay $400 for the console. The manufacturer would like to charge $400 to JS and $200 to BZ. However, to do so blatantly would be illegal. It might also be impractical--what is to stop BZ from buying two consoles for $200 and selling one of them to JS for much less than $400?
The console maker looks for ways to price discriminate. There might be a "standard" version of the console that sells for $200 and a "deluxe" version that sells for $400. If the features in the deluxe version appeal to JS but not to BZ, this will work. Or the maker might release the console initially at a price of $400, wait three months, and cut the price to $200. If BZ is willing to wait but JS is not, then this will work.
Back to the original question, temporary sales are often a tool for price discrimination. If you need something now, you have to buy it whether or not it is "on sale." But if the purchase is discretionary, you may only buy it "on sale." The store keeps its prices high ordinarily, in order to pick up profits from the price-insensitive shoppers. The store puts items "on sale" on rare occasions, hoping to pick up profits from price-sensitive shoppers. Unfortunately, they lose profits from price-insensitive shoppers who happen to come in the day of the sale.
The beauty of holding sales on "Black Friday" is that stores know that many price-insensitive shoppers will stay away in order to "avoid the crowds." So you can get revenue from price-sensitive shoppers without sacrificing profits from price-insensitive shoppers.
