It’s a great tool but shouldn't it be the client using that tool in some form?
For example in my case I have a bunch of alien plants and my experience is that clients usually buy multiple of them but never in same order, they for example take type 1, 2, 3 and 4, but not take 5 and 6, then someone ells comes along and takes 2, 4 and 5 but not 1, 3 and 6, etc.
This makes it hard for me to predict what should go in a collection.
It reminds me to the successes of Napster and MP3 in the old day’s, people could instantly create own CD with just the tracks on them they liked, people had always silently hated it that a CD usually had multiple tracks on them they did not like but jet needed to pay for them.
Maybe something that clients could do on the spot and get 5% tot 10% on the total amount would work even better?
