WHAT U do is when u have an item up thats for exact shipping or any item.. if u dont dont have a scale to weigh ur items which i baught me one on ebay for like $20 lol it will weigh up to 50 lbs but it was on sale i think but yea u take ur item to the post office and have them weight it and u can check the shipping price on usps.com u click calculate shipping or w.e. and put in ur zip and their zip and click package unless it in a big envelope then u click that option and u put in the weight and well it tells u from there u click that bottom button and u will scroll thru the options u will pick whats cheapest.. wich usually priority or first class ...
