Bought a set of rotten eggs at Lian Hua Supermarket; the produced date was the date of purchased. I had specifically chosen a set of eggs with the longest expiration date and to my shock and horror the eggs were all rotten.

The most obvious reason was that the eggs had been on the shelf for so long and was not sold out and hence the tag was simply switched out and continued to be sold. Things only get better if someone complains!!!
