When you're getting an overseas shipment from a full-service carrier with brokerage services like UPS or DHL Express, you'll typically get an invoice in your email from the carrier once the package clears customs. If you pay it quick enough, it doesn't really slow down delivery.How did you find the customs fee?
I got an invoice from $96 from UPS once my seaskin hit customs, but the lions share of that amount turned out to be duties due on the undergarments, not as much on the suit itself which was deemed sports equipment rather than apparel.
UPS didn't provide an itemized list until after delivery. You pretty much just pay whatever they're asking, and expect a duties bill somewhere betwen $50 and $150 for a US destination depending on what else is on the order and how it gets coded.
