Absolut Vodka [Produced in Sweden] - Should I Put My Collection Up for Sale?

Many friends are aware i don't club and that i am a really weak drinker when it comes to alcohol. The two aforementioned conditions, however, didn't dent my interest to collect beautiful bottles of duty-free Absolut Vodka whenever i returned from an overseas trip. 

I amassed quite a good quantity and this would have continued if not for one simple reason; space and the lack of it. 

Since the bottles are now collecting dust and placed in a dark location hardly befitting of their glamorous status, i have been deliberating on the option to sell the entire batch to interested parties (my parents would be so glad to read this)!

There is a question mark in my mind though - would i flout any Singapore law since i don't have the license to sell alcohol and i got them without paying any duty?

Would be grateful for any enlightenment! 

[Update]
 Sorry as i have decided to keep my collection intact. According to some well-informed friends, it might flout some existing law on alcoholic sale and i thought it best to keep them for further dust collection. 

Thanks for all the interest!
