I buy a lot of our food in the bulk section at Sprouts. I prefer it that way because it's usually cheaper and I can control how much of each item I purchase. Instead of keeping them in bags, I put them in containers:
I went to Dollar Tree (who follows me on Twitter, by the way) last week and bought the small plastic containers. They were 6 for $1. What a deal! Then I simply wrote the item on masking tape and stuck it on the corresponding container. The other plastic containers are ones that I've picked up along the way from garage sales or thrift shops. I love a good Tupperware find for cheap.
Here is my end goal:
There are few things that make me happier than: 1. a clean kitchen 2. an organized refrigerator and 3. an organized pantry.
