Kmart offers the Rubbermaid Lunch Blox Sandwich Set, model no. 1806231, for $7.97. Opt for in-store pickup to dodge the $5.75 shipping fee. (Amazon offers it for the same price with free shipping for Prime members.) That's pennies under our mention from last week and $2 under lowest total price we could find elsewhere. Designed to save spaces in lunch bags, these reusable containers are BPA free and dishwasher-, microwave-, and freezer-safe.
