There's a Penzeys near me as well, great place. If you're looking for an unusual spice it's probably there.

They recently had a special -- it might have been for catalog subscribers -- for a free jar of spice, so last time I was there I picked up a free jar of the sweet curry powder, and bought a jar of their new minced garlic (it's dehydrated, not a garlic salt), which really comes in handy when we don't want to mince whole garlic.

Their catalog is a good read too.
