It would be best to summarize rather than post links.  :-)  That way
we can address your interpretation rather than our interpretation.  I
might see an entirely different abuse than you!

If that means keying in the price of an item, yes, one could mangle minivend
so it would do that; but not the stock install.

Yahoo stores last year let one enter the price into a get string, not even
a hidden string.  At least the seed catalog store I use did.  I noted that
that convenient order entry is not available this year when I orderd this
past weekend.  :-)

Last I played with Cybercash that was all encrypted.  Still, we've not
used Cybercash for several years now;  all of our merchants have moved back
to their regular processors.
