I finally got to Bottlebuys and I liked what I saw.
Milagros Silver tequila, $33 in Stew Leonards, was $19.
Jack single barrel Daniels, high forties elsewhere, was $40 here!
They had a 24 proof coconut rum for $13, and decent prices on Spanish bubbly, Freixnet 1.5 litre for $13.
It has a warehouse feel with lots of product displayed, but not much of a selection.
I guess they keep prices low by limiting the selection like the liquor store next to Costco in Westbury.
