You probably wont find an actual supplier that will ship anything less than $5. Mainly because on something like a spool of thread they are only making about .50 cents profit so it's not worth their time to pack/ship something like that for less than $5 shipping.

Is the code for the green/silver you want 062? if so and you can wait a couple weeks then next time I place an order with my supplier (which will be in a couple weeks) I'll order you a spool and when my order gets here I can just drop it in a padded envelope and send you which probably wont cost more than about $2 shipping.
