I’ve posted some price comparisons and comments about the Kosher food selection at the new Waltham BJ’s on this page.
Executive summary: You can save a lot of money on the stuff they carry, but the Kosher food selection is bad.
I’m going to keep updating this page with additional pricing information and any changes to the Kosher food situation, and I’d appreciate pricing updates from others, so send ’em in if you’ve got ’em.
