Walmart offers the Seal-a-Meal Vacuum Food Sealer for $27.04. Opt for in-store pickup to dodge the $5.99 shipping fee. (Amazon charges the same.) That's the lowest price we could find by $4. It creates an air-tight seal around food with the four included 1-quart Seal-a-Meal bags. The bags are puncture- and tear-resistant and durable enough for the microwave.
