I love buying from Aliexpress. To get the last star, there need to be a bigger security in terms of refunding which can be a little tricky. My last purchase was a replica Omega Seamaster. You can see pics and read about it here:

When you know how to navigate on Aliexpress, I think it is the best and cheapes platform there is.
