Doesn't surprise me either. Anecdotal story coming, but there is physical location on Philadelphia, and I stopped by as I needed an item for dinner that night, and it was on my way home.
Store was kind of bare, and poorly organized. But the kicker is they didn't accept any form of mobile wallet! They had an identical POS system to wholefoods which takes it just fine.
So I quickly put my items back and headed to Giant.. Haven't been back since
They have a good price on take out pizza. Unlimited toppings, and with Prime membership it's $8 something for a large pizza. It was probably their loss leader to get people in the store. I felt like the store was usually pretty empty when I was there. I wonder if Amazon will keep Whole Foods too.
