If you know the weight take your zip code and go to USPS.COM to (calculate a price) put in your zip code where it says "from" and my zip code 33990 where it says "to" then look for 1st class shipping or standard and put the weight of the package in it will give you the cost for shipping. That is how most sellers do it. A lot of people want to know BEFORE they bid how much it's going to cost to ship. Also you should mention in your auction how the shipping is to be paid, ie* Paypal...
