2. Coconut and Olive Oil. ALDI has the cheapest price on coconut oil that I’ve ever seen. It’s organic and unrefined for $4.99! Coconut oil is a must for cooking eggs, lean meats and all sorts of other things on Whole30. I use coconut oil daily whether on Whole30 or not and I would never buy it anywhere else! You can also score olive oil for a great price. And now ALDI has coconut oil cooking spray!!
