Bunnings have the AEG 18b blower and trimmer kit with two 5ah batteries and charger going for $350. They used to be $499 last year then it came down to $450 and now $350. You also get the bonus charger via redemption from aeg. The blower it's self with battery and charger goes for $299 or the trimmer as a kit with batter and charger goes for $399, so this is damn cheap…
Not sure if they are clearing or what, but it's on the bunnings and aeg websites for the current price of $350. The only thing I can think of is they are discontinuing the 5ah batteries with the new 6ah fusion units coming out but that is just my speculation. I have these and they are great. I paid $450 x for the kit.
