Frugal it's not, but for busy New York City professionals time is money and Freshdirect does save time. Luckily, their product line has also improved recently and there are several wild local seafood options and even a limited selection of grass-fed local meat. I usually only use Freshdirect if I'm working on an important project with a tight deadline. Despite being kind of expensive, it's a lot cheaper and healthier than the alternative when I'm busy...which is eating takeout.
So what's good at Freshdirect?
