I Combine shipping but you will need to add items to your cart then request an invoice from in your cart. This is easier on a PC rather then a cell phone.

Ship as many singles items as you want for one price 
Trading Cards - 3.50 (first class shipping only)
Comics - 5.00 (in cardboard comic mailer)
Records - 5.00 ( in cardboard record mailer)
other items ship per estimated rates depending on your location. I will also combine all of these items but will need to get a packed weight and also sent an invoice.
 thanks
