[updated commentary part one]
It is quite some time after my initial post and I've noticed that all we've got is the broken Robert's Fresh Market site that's still broken, and Dat Grocery style services.
The Dat Grocery style solution would even begin to work for me because they are missing the very thing that makes online grocery shopping the time saver that it is. With Dat Grocery, for example, I have to sit there and enter in each item, each time, which not only is time-consuming but allows for more error. I think what most of these services fail to understand is that the delivery part of the grocery process is *not* the real time-saver. It's like five minutes each way to drive to our nearby Rouses. The TRUE time-saver is the lists, which Robert's Fresh Market does not have—but then it takes one minute to go from page to page on that site so the process is broken anyways.
When I used Peapod up north, I made lists. They would take a couple of hours to create to have our brand of mayonnaise, our favorite cereals, our favorite coffee, etc. Now this is where that best comes into play. I could then go into that list to do my regular orders and, I actually tested this once, I was able to do $500 worth of grocery shopping in under ten minutes.
I see that with Dat Grocery, you can upload lists, but then I would have to build a spreadsheet of all my favorite brands, manually copied and pasted from some random grocery site like Peapod and not even knowing whether that brand is available at whatever grocery stores Dat Grocery delivers from and trying to remember every possible brand while I'm in the grocery store and taking notes would certainly cause me to forget numerous brands. And what's more, even once I create a spreadsheet of every imaginable product, I still have to manually copy each row at a time from Excel to create whatever list I'm going to paste into the field for Dat Grocery.
