I must admit we used LO happily, importing a mailing list from a spreadsheet into a mail merge word processed document to produce formatted membership cards with a nice background image and a logo. Simple, easy, worked lovely and, as we had no money, cheap. Then an update meant only 10 images per file or formatting broke for the mail merged document ... that's only five cards and a lot of swearing when you have 200 to print ... update fixed it, then next update broke it again, two subsequent updates failed to fix it and we did the other thing ...
