1. Since you didn't mentioned any services I would recommend doing grocery shopping via internet. It's not a big time saver on the begining. Chosing products in the "real" world is faster, especially when someone is in hurry etc. But if you use shopping lists usually built into software you can do it faster and also not waste time on commuting to your shop. You even can automate that 100%. 2. I don't have experience with it but a lot of people are recommending Vorwerk Thermomix cooking robot/device.

Good luck and if you find something interesting please let us know :-)
