I certainly buy the staples, like Grey Goose and Bacaradi, and Bombay, etc. But I always make it a point to check out new stuff. It's usually hit or miss. But once in a while I score with a huge hit. The last time I went, I was drawn to a bottle of Lichido (which happens to be a lychee liqueur, as you mentioned -
http://www.lichido.com), which I'd never seen or heard of before. I bought it and fell in love and, after I introduced it to my friends and family, now everyone's got it at home. So you never know. I had once bought a bottle of Hpnotiq, because it looked cool. It was ok, but I never repurchased.
