You can get a $50 voucher to Lock n Lock for $23 today on Plum District. This would be a good way to maximize on the different great sales Lock N Lock has offered on its website lately. Like this $1 per container I shared with you two weeks ago (now expired). The voucher expires 2/16/13 so plenty of time to use it.
Lock N Lock sells air-tight leak-proof containers similar to those sold by Snapware if you are more familiar with that brand. They make BPA Free plastic and also glass containers.
