The price is very reasonable for the storage life and convenience, not to mention that they cook up great for scrambles and omelets.
Even after opening the can we have found that they are more than viable in excess of three months in the fridge without any issues (we keep the fridge at just above freezing).
From what I have seen stamped on the cans, Augason dried egg products typically have a shelf life of ten years plus when unopened.
And, the "best by" date is exactly that, a guess imposed by the FDA that states that they have to stamp a label on the can. I have opened and eaten cans of chili and the like that are almost 10 years past their "best by" dates and lived to tell about it ;-)
As always, just my $.02. Think I am broke now.
