For those who are ordering separate items (for example, some sleeves and a future YA Sleeve Pack) to pay for separate postage. Please contact Jess if you are unsure what extra postage you need.
Not sure which size? Here's what might help:
1x sml sleeve = small postage
2-4 x sml sleeves = medium postage
1-4 x large sleeves = medium postage
4+ x large/small sleeves +/- other items = large postage
