go buy some bubble wrap, tape it around the board, and the wheels, pack it in a long, cardboard box stuffed with newspaper or more bubble wrap. Weigh it, go online if you have paypal and fill in the form with the weight, dimensions of the box, and add insurance,pay, print, slap the label on the box, then put a note in your letterbox that you have a package to be picked up. The postman will come to your door, get it and that’s it. If you don’t have paypal then bubble wrap the board, pack it as above and take it to the post office.
