Query: Old, stale and a waste of my money

This flavor of thinkThin bars came very highly recommended, so I bought a pack of 10 on Amazon when they were a Gold Box deal. I was disappointed to find that every one of the 10 bars came out of its packet with that white dusting on it that very old chocolate develops after its sat on the shelf too long. Maybe they weren't old--just stored badly. The date stamped on the box was March, 2011. Anyway, they were not good. I'd really hate to think that's why they were a Gold Box deal. They might be yummy if they were fresh and/or stored properly before shipping. Since I'm too busy to go to the trouble of packing it up and standing in line at the post office, and didn't have the packing slip anyway, I just let it go, but I have to say I was really sorry not to have the joy that apparently my friend had when she had tried these.
