I am looking for 2 diaphragms for a Hailea ACO 9903 airpump. The only thing
is, when I search online I would be cheaper buying a new pump from my local
pet shop than buying a couple of rubber diaphragms online. How do the expect
to do business when 2 little rubber diaphragms cost £5 and they want £6 post
and packing.

Unless anyone knows where I can get them a lot cheaper?
