This is the best deal I have seen for a while, I was surprised that they still have stock. I think it's perhaps leftover stock from the Black Friday deal last year.
Has been selling regularly for $379 to $399 on Ebay since April this year.
Don't be confused about the models here - these are the mid-range brushless tools, not the cheaper entry level ones. The prices if you were to buy individually from Bunnings (which we obviously wouldn't do) are:
Total = $836.
Stock says limited availability but my order just dispatched from the Brisbane location. Not sure about other states/stores.
Edit: Appears as though there may be minimum order quantities in some states and it' showing as out of stock in others. Still appears to be stock in Brisbane.
Edit 24/07: Sold out in all states.
