Which is the best Saints' merchandise shop in NO?

Black & Gold Shop.

But at the risk of sounding snobby, I wish they would stock it with some simpler, classier stuff. A lot of the merchandise they carry is pretty tacky.

I've had a long-sleeve black shirt with a single small gold fleur-de-lis for years - it's gotten so much wear it's almost falling apart. but they don't offer much like that anymore, everything has huge gold swoops, swooches, spikes, and monster-font text all over it.

Not a rant at all when you are telling the truth! This is exactly what I thought as well. I did manage to find a nice Polo but that was it.
