So it was like buying tickets online? if multiple people were interested in the same region, the one which payment went through first got the region? However, this must still have been chaotic once the interest started to rise as space would seem empty until the payment was confirmed, and others would try to buy in the meantime. I guess you would also just have to make a rough estimate on the design of your banner and just buy the space, no time to design it first.
