We used We Go Shop this past March. They were wonderful and will use them every time from now on. Never used Garden Grocer so I can't comment. We had her shop at Publix and we allowed substitutions. She actually saved us enough using the store ad and 2 for 1 deals that it almost paid for the delivery cost. I received a phone call the day of delivery (we were switching from a studio to a 2 bed villa and didn't have groceries delivered until we were in the larger room) saying she was in the area before the scheduled time. I was in the middle of MK, so I gave her my cc # over the phone and also added the tip. We checked in at AK around 4 and the groceries were waiting at bell services. The cold items were grouped together and had been in cold storage.
