The First Disappointment

I ordered my last batch of buy one get the other 50% off, and the were stale. Stale to point that I could not bite my bar. If I hadn’t ordered so many of these I would’ve thought it was a normal texture, but it is far from the normal fastful bar. Unfortunately, I’ve just started this box and haven’t opened the 2nd. Fingers crossed that I haven’t bought two boxes of bricks.
