Convenient and easy! We ordered from Garden Grocer as part of our family trip to Disney. We ordered a week in advance and everything was delivered on the morning of our arrival. We checked in and the kids were starved. Before our luggage was even delivered I was able to whip up peanut butter and fluff sandwiches and big glasses of milk - disaster averted! Everything was fresh and properly packaged.
Great service to preorder my shopping in the UK for my arrival. However the website was by no means Tescos.
Everything was exactly as I ordered and delivered on time.
