I'd like to buy a variety of small bottles of scotch for a gift. I know I can get nips of the usual suspects like Johnny Walker at most liquor stores but I'd like to try other labels. These don't need to be nips but I don't want to buy full-size bottles either. For anyone who's flown through Heathrow or visited Scotland and seen the samplers there, you'll know what I'm talking about. I'd prefer a store that's downtown or in Metrowest (Cambridge, Brookline, Newton, Wellesley).
