The Basic shipping cost for one box of flies is 2.65$ By regular mail (can't tracking online,we recommand you by more boxes of flies which we can give you each additional box of flies with combined shipping cost of 0.95$ ,and if you buy over 4 boxes(including 4 boxes) we can auto change it to Registed Airmail By China Post, which most of coutries can be track online) Please don't pay one by one, when all your bid item end and won, just ask us to revise yur total invoice to reflect combined shiping cost) Thanks.
