I recently got this bread container during the Christmas in July sale. It wasn't one of the clearance items, but I used the 45% off code and got a good deal. I've been wanting one for a while because there have been several times when we have had moldy bread because moisture gets to it or the bread gets stale before we can eat it.
Because Lock & Lock boxes have the snap lids, they're air tight. (They really are!) The moisture can't get to the bread, so it lasts a whole lot longer. Caleb goes through spurts when he wants other things besides sandwiches for lunches, so a loaf of bread could last us quite a while.
I have also begun putting bags of chips and pretzels into L & L containers. They just last so much longer in there and I'm tired of taking the chip clip off of the bad and biting into a stale chip! Yes, the boxes are a bit bigger to store than a rolled up bag of chips, but I'll make space if it means that I won't waste half the bag because I don't eat them all the day I open the bag!
