I kind of read some about it in another post but that still did not covered what I wanted to know.
So basically everything's 50% OFF. I get that. How about the Cash Shop Credit itself?
Whenever I buy CSC it always takes more than a day and a ticket to have that solved and I don't want to miss anything from the Black Friday. Should I buy my credits ahead or is there any important discount when buying CSC during the Black Friday with my credit card?
No, the question is, is there discounts for buying Cash Shop Credits during that time as well? (I know there's no admins during weekends so it'd be also a mess if I tried to buy just when weekend starts but I want to make sure.)

Im pretty confident you dont get 50% off on CSC. That essentially means you get like 75% (? i cant math in the mornings) off.
In fact, i dont even think you get 50% off on everything (especially if this year they do bring back older collections/research notes).
But i wont be surprised if Keith does those paypal/stripe deals where you get an extra 25% csc or something like that the weekend before or the weekend of.
