If you don't want/need 50#, find a like minded friend and split the cost. 25# for $10, about what a 10# bag costs.
Check Asian grocery stores, sometimes rice is even cheaper there, restaurant size bags.. I’ve also found that Asian and Mexican grocery stores have the best deals with ingredients you can’t get other places...
I get bulk spices at Asian grocery stores.. A small jar of whole cumin seeds at Kroger costs about $5.00, but for that price at my local Asian grocery, you can get a half a pound bag. (only buy whole spices in bulk like this as spices spoil fast when ground.. toast in a dry pan before grinding)..
Sounds like a good idea. Think I’ll pick up a couple of those.
