That is a really good point, I actually got someone else to get it from the play store then copied it, the updates from apkmirror are then fine since the signatures match. I'll edit the post to say, get it from a trusted source.

This is also useful: http://www.onyxbits.de/raccoon It's a dektop play store client. I tried it out a while back and it worked, don't know about now.
