In the beginning, there was GraphCalc. It was free, and things were good. Then we, the authors, started incurring many expenses. We asked for donations, but didn't receive enough to cover our costs.
So, we started to charge for it. But that didn't make much money either. So, we are going to spend less time developing it, and reduce our costs and just give it away.
There is no more purchasing. GraphCalc costs $0.00. No tax, no shipping and handling. You may use it on 1000 computers without paying anything. Although, if you find it tremendously useful, and you'd like to see it advance you can encourage us to do so by sending us whatever amount you like.
