What's the best place to buy comics online?

[James]

I just want to get the Gargoyles comics. :/ It's not worth driving to the nearest store just for that comic, and I don't know what online stores are reliable adn trustworthy.

I could order it on Amazon, but only if I can find another 20-some bucks of stuff to buy for the free shipping. I can't do that every month. :/
