Ha! I figured out the reason even before I read the whole article... always a gratifying feeling.
That said, there are tons of food hacks if you want to save 30-40% and have a strong stomach. Buy your cashews, cumin seeds, turmeric, groundnuts, papayas, guavas from the nearby Indian store - there's tons of them in CA. Most of these are sourced from Fiji, Philippines, India etc, whereas Safeway would source cumin from Oregon and charge $5 per ounce. You can literally get a whole pound of cumin for that price - but no, you don't get the "organic certification", or the bar code or the USDA assurance sticker or anything that lets you know where the cumin came from in case you get some food poisoning and want to lodge a complaint. The Indian store lady dips into a giant cumin bottle and pours out a pound of cumin and takes $5 cash and no sales tax ofcourse wink wink. So yeah, depends on your ethics and cash situation. Say you want a little pep in your walk and like some extra endurance - used to be ephedra was legal and you could pop into your Chevron foodmart and buy a pill. Now it's no longer legal, so you go to the Chinese store and get the strongest ephedra tea - free market ftw. Ofcourse if you brew something strong and land up in the hospital, the medic can't really help you since who knows where that tea came from and what else is in it. Literally no American supermarket can compete with an Indian store when it comes to say cashews. Your Target gives you two pounds of cashews for $15. The Indian store gives you two kgs... that's 4.4 pounds! Ofcourse it won't come in a nice airtight jar with feel-good marketing on why you must eat your servings of USDA nuts for optimum health - instead, it's going to be wrapped up in a cone made of newspaper.<p>If you have a "tropical palate" and a strong stomach, you should definitely try some of these shady joints. It's a trip.
