Is there any reason to get paper reprints of your articles?
I did it initially so that I would have a nice paper copy of my paper. In principle I could hand these out to my colleagues and other people who were interested in my work.

This is rather out-dated these days. You can just send interested parties a pdf and they can read it on their iPad. Save the trees.

I don't see any reason at all to actually pay for reprints. You have a copy already, right?
