Groceries are a bit expensive on the whole (1-3 dollar mark-up more on items than what I'm used to, and I tend to shop at Whole Foods), but I suppose that's what you pay when someone else is shopping for you.
The website is pretty clear (missing some pictures), but altogether lots of options. The lady was friendly on the phone. For next day gifts and groceries when you can't do the shopping, not a bad deal. :)
