Some people call plugins what in reality are "alpha transitions" or ready-made effects delivered in the form of movie files. We also call them "clip-ready" transitions.
It is very likely that Marti is buying some of these.
If that was the case then Marti all you need to do is store them in a drive and/or folder that are easy to access, safe and suitable for editing purposes and import them into FCP like you would any other .mov file. I would also reccomend to back up those files in case you lose that drive because of mulfunction or any other cause.
