Had been away for a couple of weeks and went to the Dedham Costco today. Was surprised and delighted to find that they now sell alcohol. It appears to be the same as the other Costco liquor stores but they said it was a separate company, that's how they get around the state law of 3 stores allowed to sell liquor. Also, you don't need to be a member to shop there. Wondering if anyone has any feedback on prices/selections.
