I had used gardengrocer.com on a past trip.. We were so happy with how convenient it was, I used them again on this year's trip. We literally ordered all toletries and other essentials. I have recommended their service to friends and famly who have also placed orders. Rest assured that your items will arrive fresh and on time!!!
I really can't think of any suggestions for improvement because I can't imagine it getting any easier.
I used GardenGrocer for the first time and I was amazed how well it went. They called to confirm my order. The order was checked to be complete and it was delivered on time. It saved us valuable time to do the things we needed to do as a family. Loved the service!!
