IMPORTANT! PLEASE READ! FIRST CLASS PACKAGES CAN ONLY SHIP UP TO 13OZ. ANYTHING WEIGHING MORE WILL SHIP PRIORITY MAIL, WHICH IS ALSO FASTER. MANY, BUT NOT ALL OF OUR LISTINGS GIVE BOTH OPTIONS. WHEN CHECKING OUT, IT IS UP TO YOU THE BUYER TO MAKE SURE THAT PRIORITY MAIL ISN'T GOING TO BE CHEAPER. IF YOU ARE BUYING MULTIPLE ITEMS, IT OFTEN TIMES IS CHEAPER BECAUSE OF THE WAY EBAY CALCULATES THE WEIGHT WITH FIRST CLASS PACKAGES. IF IT IS CHEAPER, WE WILL NOT REFUND YOU FOR SELECTING THE WRONG OPTION. WE ALREADY HAVE IT SETUP FOR EBAY TO COMBINE THE SHIPPING WEIGHT AND COST OF ALL ITEMS IN YOUR CART. THEREFORE, YOU WILL NOT RECEIVE A REFUND ON COMBINED SHIPPING NO MATTER WHAT, IT ALREADY IS COMBINED. EBAY CURRENTLY HAS A BUG IN THEIR SYSTEM WHERE IN SOME OF OUR LISTINGS IT STATES WE HAVE FREE SHIPPING FOR ADDITIONAL ITEMS. THIS IS NEVER TRUE FOR ANY OF OUR LISTINGS. THE PRICE ON THE FAR LEFT SIDE IS THE FINAL ESTIMATED COST AND WILL GO UP BASED ON THE QUANTITY YOU ENTER. FOR ANY LISTING THAT GIVES A PRICE FOR EACH ADDITIONAL ITEM, THAT PRICE IS CORRECT.
