I absolutely echo Balakin's and FluffySheep's comments re: prices and in particular how certain US individuals whine about the delivery time. I used to shop around the amazon.co.uk marketplace and wait for deals from 2 online Polish comics retailers multiversum.pl and atomcomics.pl
I now predominantly order Omnibuses from IST and bite the bullet regarding the shipping to Poland, reminding myself of all the previous fantastic deals and glitches I found.
I can not fault IST. Best packing and best customer service I have ever experienced. The bees knees!
