Where can I buy a replacement drain plug for skimmer cup?

[duncangweller]

Hi all,

Whilst cleaning my skimmer cup earlier I lost the drain plug (the little rubber bung) down the drain in the sink.

Does anywhere know where I could buy a spare? Its a reef octopus skimmer and they have them on their website for $3 but I'd rather pick one up locally if possible than order it online and wait forever.

Thanks for your help,
Dunc
