did you not try it first, they give you 45 days?
wcp seem a good bunch, i tried it a while back, but wasn't able to put it through it's paces, got in touch and was given another trial. I like that you can put a time for the job, so you can see how ling the day will be.
still not sure, as george does what I need. any jobs that have two prices i just put in a note that shows on the print out
