IF YOU ARE LOOKING AT INTERNATIONAL SHIPPING READ THE SHIPPING INFO FIRST - DDU means "duties and taxes unpaid", which means for example for the UK a cash on delivery charge will be required when your parcel is delivered and this will be 32% of the purchase price (20% VAT and 12 % import duty).
I placed an order with Nasty GAL without understanding what this meant - so be warned as I learnt a very expensive lesson!
This is not the fault of Nasty GAL I should have done more research or asked questions of their customer service team before buying.
I found the customer service very good actually kept me well informed and were helpful when I had to deal with the COD charge and return of items went smoothly.
