"Picked up on Black Friday" ... Oh dear. Do you know what that was like when this first started in US???? Now, "Black Friday" is any chance, as you say, "to have a sale." Those sales were really impressive. in the beginning. Hambone's wife got copy/printer paper for 1 cent a ream!! Lots of people waited in line, long lines, waiting for certain stores to open. It became a real event; almost like a party.
Then ... maybe even just the next year ... Black Friday went on-line! Not the same any more.
