I came into a very large box of baking chocolate and have had it for several years, in my unheated basement, in the dark. Still good. I am making goodies as fast as I can!!
It slays me how the exp. date on your meds is magically 1 year EXACTLY from the date the scrip was filled. Who knows how long it was on the shelf at the pharmacy, but as soon as they fill it, BAM the clock starts ticking.
I take all this stuff with a large grain of salt. Which has no expiration date, as far as I know.
