CoolSpike :
Ok thanks for all the help, but I dont know if I should buy them in November or December. Cyber Monday or Black Friday?
Black Friday and Cyber Monday are concepts, not dates.
"Black Friday" lasts from 1 November until 15 January.
"Black Friday" is the theoretical date when a company that earns a 10% profit for the year is actually in the black. 10% of 365 is 36 days. Right around Thanksgiving. A lot of people have a 4 day weekend, so...the day after Thanksgiving, being a Friday, becomes a big shopping day.
Cyber Monday came about due to people (years ago) having a much better internet connection at work than at home. So they would go online at work the Monday after the 4 day weekend. Online retailers noticed this sales bump, and writers picked up on it. So now 'Cyber Monday' is a "thing".
In reality...BF and CM are just names for sales of random old stuff between 1 Nov and 15 Jan.
You should buy the parts you want, for the price you want to pay, on the day when you have the money available.
There is no special 'day' for your selected parts.
