I just got an order in from Arrow that I spent $50 on. $40 came from the US, in one box that's a bit large but not terribly so.
The rest... 5x BNC connectors and 2x LM1806 voltage regulators. A small padded envelope would be sufficient, but they came one SKU to a box. Two lunchbox-sized boxes, shipped from the same warehouse in NL, with customs form and invoice envelopes in English and German.
Sent priority overnight, although it actually took two days.
I'm having a very hard time believing they spent less than $20 on shipping this order. But I guess the free overnight shipping offer got me to order from them... once, because their website is a three-alarm dumpster fire.
