Contacting Fischer's head office in Austria worked for me. I first called them, and was given someone's E mail address (again, at the head office in Austria). After a few back and forth E mails, things eventually got moving (I did have to push the individual after nothing had happened for over a month, despite my being told that they would get me the grommet strips). Beginning to end was probably about 3 months - but I got 4 old Vac Pro 90 grommet strips sent to me for free.
Well - almost free. I did have to pay for the initial phone call (perhaps 39 cents).
