Shelled you failed to tell them to reduce the invoice.
All Asian retailer you can get them to put 0-100% invoice.
RWA is weird with buying guns now, they'll only deal with retailers and almost every retailer here wholesales with them.
Don't know why you guys getting duties from them, but I always order from wgcshop and ehobby and never have duty ptoblems. Only time I get duties is from evike with guns.
