My only suggestion would be that the people who are going to buy numbers "at the end of the month" choose their numbers now. Even if they pay for them later, the numbers should be selected before the 26th.
I understand that the chance of any ball coming up is the same regardless of the prior drawing, but it just seems like the right thing for everyone to be on the same footing by choosing their numbers before the original drawing.
Personally, my number was chosen after extensive consultation with an astrologist and numerologist based on the positions of the moons of Jupiter on the 26th.
