Buy- Olive Oil
You can use olive oil in just about any cuisine out there. It is always wise to keep some in the kitchen, so your best bet is to avail of the big options that you can get at Costco. This way, you will always have bottles in stock at home. It is not only cheap, but it is also extra-virgin, high-quality, and organic!
Don’t Buy- Ground Coffee
Coffee is always on the top of our grocery list. We simply cannot get through the day if we did not chug a cup of java. If you can relate to this, you better listen close. Even though you can cut corners by buying a bigger size, you should never forget to prioritize the taste. After the coffee beans are grounded, they get exposed to air and lose both strength and flavor. The smaller size is better if you want fresh coffee.
