To the best of my knowledge people who collect the older perfume bottles usually keep the old perfume in the bottle. They are never going to use it and nothing smells worse that getting 70 year old perfume on your hands. On top of that they would prefer to have a bottle with the old perfume in it
First of all you are not going to use the perfume. Secondly you do not display your solids open so what is the big deal about discolored perfume.
Personally I dont care what condition the perfume is in when I find a solid I have been looking for. <img src='style_emoticons//smile.gif’ border=’0′ style=’vertical-align:middle’ alt=’smile.gif’ />
