I combine shipping on multiple wins, all you do is pay the highest shipping amount from the auctions you have won, and then you pay half of the shipping amount for each additional auction. Insurance is 1.50 for multiple wins unless the total is $50.00 or higher, if over $50 the insurance rate is $3.00. Payment must be received within 7 days of auctions close. If you plan to combine shipping do not pay for anything till you are done bidding, When you are finished email me for a invoice and I will adjust the shipping for you.
