Diskettes are a lot cheaper than they used to be.
But, they can be found for much MUCH less, if you know where to look. By buying in quantity, you can save a large amount of money. These are used diskettes, mostly from software companies that had thousands of their diskettes produced, but find themselves with excess, outdated diskettes. These diskettes are erased, new labels are put on, and they are good as new. The prices listed here were current at the time this was written, but they might change, so be sure to get their latest list before ordering.
