sorry for the thread necro, but these guys are total shysters.
They are UK based. If you use their actual UK site -
www.ubyk.co.uk - you get presented with a set of prices + delivery fees applicable for the UK, EU states, USA, most of the rest of the world. You can change currency (including to $AUD) but the underlying price is the same.
Australia as a delivery option is however blocked. When you query this to Ubyk, they instruct you to use their Australia specific site
www.ubyk-pro.com
ubyk-pro.com immediately increases the prices of anything by a minimum of 25% for no other reason than being in Australia.
I asked for Ubyks comment as to why is this but they declined to respond, so name and shame.
