Hi all, I don't see it on Coles online, but walked into Coles World Square right now and saw this water flosser for 22 bucks. Seemed pretty alright. Previous deal I could find was $75 - https://www.ozbargain.com.au/node/740196
I imagine it may be in limited Coles in store and not knowing whether there's enough over the limit for OzBargain, figured I'd make a forum post and anyone walking by the dental section of their own Coles may want to scope it out if they're interested in one.
retain the receipt - the device is great but prone to failure after 4-5 months of use.
