From Wikipedia/Random.org:
To make sure nobody places unfair demands on the system, a limit to the number of bits supplied to a particular IP Address is enforced. Every 24 hours, up to 200,000 bits are added to each IP Address' quota. Once the quota has reached 1,000,000 bits, no more will be added. One can buy different amounts of quota top-offs in order to raise their quota, in which case the 1,000,000-bit limit is no longer enforced. The price ranges from between $1 and $5 per million bits.
I don't know how much CC is paying (or even if they're paying), but 1,000,000 bits probably doesn't last long on this site. If they're smart, they would save old sets of data and whiten it with new data in different combinations to generate as many random numbers as they need for free.
And for anyone who hasn't seen the start of all this:
