I was in Westfield Doncaster today and Sweet As in Westfield Doncaster had plenty of Lindt Swiss Classic 125gm for $1 per block. The flavours available were some blueberry type and the one I got which was raisin and gently roasted haselnuts and almonds. These usually retail for $4+.
Wish I had bought more than 1 as they were yummy even though expiry date was 31.05.2010.
Check out their website as there are more specials on there.
This deal is available @ all Sweet As stores. It's a regular thing, however, the flavours do change store to store, week to week depending on what is close to best before.
