Hey Rich what was the discount? I find the prices at
fishbookstor.com are very reasonable. I've bought many from them. He always ships quickly and packs well.

Their regular price for the Aquarium Journal Marine edition there is $25 and he will ship to Canada. so it may not be worth doing a power buy. Plus he has good prices on many other books. Or we can set up a power buy with him.
