McCormick’s spices are good and I have quite a few of them in the cupboard. For spices I use a lot of I buy direct in quantity and even better quality. A lot cheaper too.
Never heard of Penzey’s Spices.
There is a homegrown salvage grocery with a deli and butcher counter in my area. They sell spices in bulk containers, all kinds of weird stuff for a couple of dollars each.
