In the latest Kmart catalogue, Kmart is selling the Logitech S125i portable iPod speaker dock for $29.

The offer starts on 25/3/10 till 1/4/10.

This is even cheaper than the one advertised in a recent post here for the same product:

OfficeWorks is also selling the same item at $74:

..so maybe you can grab the Kmart catalogue and get another 5% off from OfficeWorks (making it $27.55)? ;)

[Update] - as has been pointed out, OfficeWorks has quickly matched Kmart’s price on their site and in-store for also $29 (so no 5% discount unfortunately):
