Crembrulee, If you do not declare and get caught with any of the fore mentioned items you will have a big problem and will have to pay duty. Get the proper paper work filled out and sent to customs and declare the school supplies and you will have "no problem". Customs agents have heard all the bs lines so don't insult them and remember the customs agents do decide how much duty you will pay.

I want to be just like Capt Jeff when I grow up!
