UGH! Invitations

I think this is my least favorite part of wedding planning. I finally found an invite I like and ordered them off the internet. The only problem is that I need to print them myself, or take them to a printer.

Has anyone ever done this?

What do they charge?

If I print them myself, will it look tacky? (I've done other invites in the past and people had no idea)

I know its time consuming but I actually like doingthat kind of stuff.

Any thoughts??
