If you are in Canada, which it appears you are, you need to be aware of the shipping cost from Heritage or even Comiclink. Heritage will charge around $50 (USD) for a slabbed comic and you may also get hit with import fees which, depending on the price of the comic can add another $20-30 to your purchase price. Comiclink also charges around $70 for shipping a single slab north of the border. For the shipping cost alone, I am always wary about buying from either of those two unless I get a great deal on a book I need.
