LS1 edit trade?

I own a 4 license version of LS1 edit with three other guys. I would like to switch to HP tuner they do not. Can I trade in my license and what is value? I assume I would send you ls1 edit cable and you would kill my vin on it?
If this does not work how would it work if I could talk them into it and what would price be? we have 4 different year model corvette C5's.
Thanks

I think the trade in only works if you send the cable in and that's it... they can't wipe the vins on it... that's carputing proprietary

As for pricing... you'd pay the 499 and could get 2 licenses there, then 199 for 3rd license, 199 for 4th license ... so the cost would be about 225 each to switch to HPT ... less the value of the cable for tradein
