I have always been scared of buying things online, a lot of vendors are mean, you will order for something nice but what you will get is something different. it happened to me not long ago and I have learned my lessons hehhe.. but then it doesn't mean that every vendor is like that, your case proved some just.

Many sellers needs to check some of their goods in the store and do away with the expired ones if not they may soon lose most of their customers, I am sure the person doesn't even know the goods were bad. I just hope you complained to them afterwards sha. Sorry about that experience
