the 120 is $6.99, so maye it was initially listed as a typo?
Also (and I didn't follow this closely) weren't the earlier 220 rolls, not factory done, but rather a guy that bought some bulk and was doing it himself? I don't have much use for 220, but for those that do, its would be interesting to demonstrate demand (if such demand is there.) However for over 2.5 times the price, it seems like it might dampen enthusiasm. The 620 and 127 are in the same price range of 220, but don't benefit from the additional frames, but they may make some shelf queens occasionally usable.
