I've had luck using these guys in the past...good quality, and you can buy varying bulk sizes. Not sure if you need 25 lbs of paprika, but if so..this is your place. LOL

Another one which ain't bad for Pantry spices is Badia http://www.badiaspices.com/
I never bought in bulk cause I can get it locally from Jewels ( Albertsons )

Tones from Sam's Club. They have all the basics (garlic, onion, chili, cayenne, paprika, black pepper, etc.).
There is also a place called The Spice House. Similar to Penzeys, but I think a better selection. I check them for the harder to find spices.
