Parfumsisabelle, thanks! I thought about delivery, but I guess it's pretty expensive... So I'm wondering whether I should bring like 10 packs from home or maybe it really will be easier to order.
I get them from GetLenses in the UK. They ship internationally and because the weight is not heavy, the shipping costs are reasonable. But you need to know what you need.
I also take a few packs back from Europe when I go there.
