Sorry it's all about the midterms this week. I haven't chekced many of the PMs in my mail box.
If you wanna order some extra (that's said like no more than 10 keys), you don't need to pay any extra on shipping. If you wanna order another 37-keyset, I'll need to re-calculate the shipping.
I'll get back to all the PMs tomorrow night when I'm done with my exams.
