I've been waiting impatiently for Binney's to open here since it's been announced. My family frequents Binney's in the Chicago suburbs, and the prices are unbeatable.
Before this Binney's opened, I would hit up Meijer, Sam's Club, and Friar Tuck for alcohol, depending on what I wanted. Friar Tuck is notable for having a great selection, especially when it comes to some of the less common rums I use. The selection at Binney's is fantastic as well. The prices at Binney's range from comparable to much better than those at Friar Tuck. And that's not even taking the weekly sales at Binney's into consideration.
With few exceptions (I think soco is still cheaper at Sam's, but I haven't checked prices there in a while), I will now be doing most of my alcohol shopping at Binney's.
