Sounds like you may have found a solution however I thought I would post this for others reference.
Officeworks has a 5% price match/beat guarantee. They will match and beat any legitimate bricks and mortar computer store within NSW. You just need proof of a better price, they may check it however.
In this case the cheapest my recommendation would be the
LG W1943TE 18.5" Widescreen LCD. This LCD normally sells for $117.
However MSY which they know all too well about due to previous price matches sell it for
$99. Therefore you should be able to get for under $95.
Although above is only a small saving, they all count and generally there is a much bigger price difference and therefore more saving.
I hope that makes sense.
