Peter told me it is $5.00 per car.
When I sent the ISP43 cars back to Peter from western Canada it took 12 days, I don't know what it would be from the states, probably about the same. The race is on the 26th so there is 17 days left. Europe would be a shorter time, I'm thinking. If there is a hold up it is customs not the postal service. Don't delay, you better get them sent!!! Mark the cars as gifts, value $20.00. and they should fly under the custom's radar.
We used the entry fees to ship the cars home after the racing but we charged a lot more per car for that one. There was not much money left ( a couple of dollars) after all the cars were sent home. I don't know what Peter will do as this is his race entirely. I'm assuming we will all be gentlemen and ladies and make sure that Peter is not out of pocket for freight charges.
