I don't think so. If I'm not mistaken, I believe the official EA maker and team would already knew what thoughts the buyers might have in terms of trying to save money, therefore they would also come up with strategies and ways to prevent the possibility of having profit loss in selling their products. One of the ways I believe is to do something like creating a unique password just for one single user and with the limitation of number of accounts used with one EA. If more than one single users using the same password to log in to use the EA, the system would immediately detect and know that and they would therefore stop the EA from working, so on and so forth. In short, for serious EA developers, they would never allow such attempt from buyers.
Furthermore, I have checked their website last time and I think they do invented such security system to prevent things such as group buy and use. So if anyone wishes to use this EA, sorry I think you would have no choice but to buy and use it as an individual. It's that simple.
Last but not least, not all traders gave good comments about this EA. Therefore, do make your own judgement and decision on whether this EA is suitable and good for you or not. For me, I will move on with other EA instead of this one. That's my thought on this EA.
