Any idea of best by date?
Hi there. These are being pulled from Amazon inventory so that information isn’t available. That said, Amazon is [usually] pretty good at removing expired inventory.
(Please note: I don’t work for Woot, I just volunteer to help out here on the forums.)
Mine arrived today in a pretty crushed box & expire August 11. I wouldn’t have purchased if I’d known, and I never thought to ask that. I’m pretty sure my family & I can’t down that many in a week. Nor is it healthy. And half the bags are probably crumbs. 
Salad topping!
