Because who buys spices at the regular grocery store, it's like $4 for a 50g bag. You gotta go to the Asain grocer or Indian market for those delicious half kilo bags for $6.
Then put them in an old pasta sauce jar and shove them in your pantry and let them get old and off gas their aroma until they're just bland sawdust....but act like you're still better than other white people because you own spices.
