Dan thanks.

I'm learning here about custom solutions and work-arounds. That's great!

I'm no expert on the technical loopholes so I welcome the input.

My arguement is simply that if it's a funnel being fed prior to cart opening then for most incentive and maximum fairness to the affiliate, leads should be locked-in. If the system is open, however, then certainly last-cookie is the only fair way to go.

Thanks for the discussion.
