In 1988-89, we used to line up to get Habs tickets at the old Forum for about $12 I think it was when they went on sale at the beginning of the month for that month's games. My buddy, who used to go with me, says he tells people this now but isn't sure they believe him.
They used to limit sales to 4 per customer. I usually bought a pair. One game I remember the scalpers approached me in the lineup. They asked how many I was going to buy at the wicket. Then they offered a deal-buy two more and they would buy them from me at face value, and give me a discount on the two I intended to keep. So I actually got those two for about $6 each instead of $12.
