Where the spices are

I was watching the Good Eats fruitcake episode last night which features a segment where he visits a spice shop. So it got me thinking: with all the variety of cuisine and the long culinary tradition in Charleston, why isn't there a decent spice shop around? And if there is, why haven't I found it yet?

So what's up? Where, besides the local grocery store, are you supposed to go for good quality spices and people who know what they're selling?
