Walmart has the Honey Can Do Round Food Container Storage Set (28 piece) for $17.30! I love using these to separate pudding and jello and they’re great for home lunches. They air and water tight and dishwasher/microwave safe.
Don’t forget if, available in your area, you can opt to pick your purchase up in-store to avoid any shipping charges. Otherwise shipping is free when you spend $35 or more.
