I found some Gillette products on clearance at the local Coles. This is because of incoming new packaging but the items are exactly the same. The 8 pack Skinguard refill in the new packaging retails for $49. See the picture for other Gillette items on clearance.
I reckon other locations would also be clearing their old stock, so check out your local.
I didn't buy any because I already have supply for 2 years. Now in lockdown, don't even need the razor any longer, just let it grow.
Maybe the got woke, went broke?
