I stole the Idea as well. Forget from who. Maybe Maven or TinMan. Oh and you guys are sooooo funny. Customs only opens the packages if the description weight and size don't co-inside. I have recieved about 15 boxes from C-bid and around 10 from trades and bombs. Only 2 from C-bid were opened all the others came through no problem. Descriptions I've recieved include, Birthday card and candy $20, B-day card and Chocolates $30, B-day gift Watch $50 and wedding candles. I once recieved a box that had cigar smoking happy faces all over it, that wasn't funny. Never never put tobacco of any kind or amount or value, they will charge duty.
Above is for USPS. If you send FedX or UPS, the package will never be opened. My wife has temped at a customs broker. All small items under $5,000 are automatically cleared assuming it fits the discription and is declared to be below $60 dollars. The packages don't even pass infront of a customs agent, it get's unloaded directly at the shipping Co. warehouse at the Airport. Good info to know for when I have a certain item shipped from Spain.
I bet the US works the same. The Co. my wife temped for is American.
