So much negativity in this thread! Just because someone missed out an announcement doesn't make them stupid.

What it comes down to (and what some other users mentioned) is that when you purchased the CSC you decided it was worth it for you to buy then. We add a bonus over irregular weekends to spur the people who wouldn't otherwise buy CSC (or see it as a worthy purchase) to maybe spend $5 that month instead of $0.

You got what you were paying for, but in the case of price changes (not bonus weekends) we do refunds.
