Some folks ship non-perishables, and other gear they just don't want to lug in a suitcase. If you need a lot of groceries, including milk, juice boxes, water, yogurt, eggs, bread, etc..gardengrocer is great. I used them in Sept and it was an excellent service. If you plan to use gg, put your order in asap...they only have so many delivery slots available so it may be tight to schedule a delivery in less than a week. If you only need snacks, breakfast items and won't be cooking, you can just tuck those items in your luggage -- will leave extra space for souvenirs to bring home!
