Walmart offers the Snapware 15.3-Cup Fliptop Food Storage Container 4-Pack for $12.14. Opt for in-store pickup to avoid the $5.99 shipping charge. That's tied with last week's mention and $11 under the lowest price we could find for this quantity elsewhere today. Each container includes a four-tab locking lid and is microwave-, refrigerator-, freezer-, and dishwasher-safe.
