I very much prefer to use MOs because of identity theft some years ago after buying from ONE site, first time I'd bought anything for a couple of months before. So now I use MOs.
One site I asked about it refused, credit cards or Pay Pal ONLY.
Bought it from another site that did except MOs, and was very surprised to find that it was the first company that was selling it on this site!!! I'm not going to worry about it, there are way too many sites on the Internet that sell stuff almost identical or better!!
