Right - so total cost from COMC is $52.50
What if those 10 cards i buy come from 4 different sellers (ie im buying multiple cards from sellers)
$8 per package to australian x 4 = $32
Thats $20 cheaper just to get them sent direct.
Spot on, at the current format the mailbox is only a viable option for PC cards, cards that are of substantial value and cards purchased from sellers who only ship within the U.S Yes you do have access to a wider range as a result but if you are dealing in bulk, particularly mass produced lower end stuff, it adds up very quickly.
If buying multiple cards from sellers who do not use the global shipping program, in most cases you only need to buy 4-5 cards before it becomes cheaper having them shipped directly to you.
