Get the most from produce purchases

I usually buy a good amount of fresh produce every week. We really like eating good produce but it can be expensive. I've got a few methods to keep produce fresh and easy to use. After all,
nobody likes to throw away produce because it spoiled in the fridge.
Grapes get washed in a colander, then cut into small bunches. I just store them in a bowl in the fridge. Having them cut in to little bunches makes them easy to get a serving at a time. I learned this trick from my Aunt Bernice.

I store many of our vegetables sealed up in Tupperware type containers. These romaine hearts have been in my fridge for a week but are still fresh and crisp.
Wash the produce and let it dry on a towel. I shake the lettuce a few times to get out any water hiding inside. Water can leave brown spots on leaf vegetables.
The celery gets cut up and washed before storing but most other veggies just get washed.
Romaine hearts each get wrapped with a single paper towel. I think it helps keep them crisp.
Jeff and I eat a salad most evening. With these romaine hearts, it is so easy to just take out one and unwrap it. Then, I chop it up with a few grape tomatoes, some red onion and any other salad vegetable we have.
I think the whole romaine hearts stay fresh much longer than bagged salad too.
Similar vegetables get stored together in a Tupperware container. Most of my containers for TupperWare Fridgesmart that I bought as a lot on Ebay. I've also got a few at thrift stores. I like the Fridgesmart best because you can see inside without opening them but I use other plastic containers too as needed.
Onions, potatoes and sweet potatoes stay in containers on the floor of the cool dark pantry.

Every few days, I check to see what produce we still have and use up whatever seems the oldest.
