I use Garden Grocer because we are usually not there to receive the order and I want to pay by credit card. I just want to get it delivered to Bell Services and we'll get it sent up later. We Go Shop charges a hefty fee (13% or something) to use a credit card & GG does not. We Go prefers that you are there to receive your order. You can specify special order items in the comments section of the GG website and they will call you with a price. If I needed to I could also specify specific sunscreens or whatever.
We usually order a case of water, Gatorade, beer, soda, milk & breakfast items like doughnuts, bagels, butter & cream cheese. The beer has to be specified in the comments section & I have to fax a copy of my drivers license. I usually just bring a partial 1 Lb bag of coffee with us as it's lightweight & squishy so I can fit it in wherever & I don't need a whole bag. The delivery fee is a lot less than renting a car for the day and doesn't waste any of our precious vacation time.
