My co-teacher introduced me to one of my greatest discoveries yet in Korea: iCoop. It's a cooperative of Korean farmers and food processors that are committed to producing sustainable, organic foods. They sell everything from eggs and milk to fresh fruits and vegetables to cosmetics and laundry soap.
Not only are most of the products actually cheaper than their non-organic counterparts on the shelves of E-Mart, but the best part about the company is that they deliver your entire order to your doorstep, on the day of your choosing. AND they'll send you a text message when they've made the delivery so you can go home and put everything in the fridge.
The only drawback, if you can call it that, is that the entire site is in Korean. (On the upside, it's a great way to learn Korean.) You'll need a Korean co-teacher or friend to help you set up an account, but luckily the process doesn't take long. After my co-teacher filled out my name, address, and ARC ID on the website, and made a couple of short phone calls to give the company my bank account number for direct transfer of funds, my account was active.
There are two membership options: one with no monthly payment, and another with a monthly payment of 20,000 원 and at least a 20% discount on all items. (So...if you spend about $100 a month on groceries, it's worth it.)
Did I mention that it comes with FREE delivery? You select the day you want the goods delivered, select the quantity of items you want, log out, and wait.
So far we've had two deliveries. The second time I ordered what I think is something similar to seitan, which was frozen, so they made the delivery in a big re-usable foam box. The next time I'm expecting a delivery I'll leave the box outside my door and they'll either re-fill it or take it back and use it for another delivery.
If you want any more info about it, please let me know. I'm quickly becoming one of their biggest fans.
