Hi Thanks for your reply.

Yes. In fact that was the first place i looked.

If you look at all the CNC routers advertised on Aliexpress you see that no seller has any feedback for sold items. and a couple have neg feedback stating the seller cancelled their order and asked them to deal direct outside of Aliexpress.
As far as i can work out Aliexpress dont support sea freight for any items. Only airfreight which qualify for escrow payment on goods arrival.
One seller on aliexpress told me the transaction would need to go through Aliexpress Escrow which supports sea frieght which means i have to pay when the goods are loaded, not received.

I guess Aliexpress dont bother removing these dodgy sellers as they still profit from sales through their sister company Alibaba.
