7.1 was the first MacOS that apple charged for, nominally to cover the cost of the CDs. 7.1, 7.5 and 7.6 all cost $29, but you could get free installers from many of the Mac magazines.
8.0, 8.5 and 9.0 were $99
10.0 was $129
10.1 was free, but a lot of stores charged a handling fee. I remember picking up my copy from CompUSA for ten cents.
10.2 - 10.5 were $130 upgrades, but there were numerous ways to get it for free. I don’t think I ever actually paid for any of them.
