I'm in the UK and would love click and collect groceries. Shopping online is the easy bit. Waiting around for a two hour delivery window is the problem especially when I drive past the store on the way home.

Something like Ernie's would be ideal. It'd even be worthwhile for collecting a few day to day items. I'm surprised Tesco hasn't done this already.

Where do you live? If you're in East London you might want to give hubbub.co.uk a try (disclaimer: I'm there lead developer).

We do really good food, 1-hour delivery windows, and same day deliveries for no extra if you order before noon.
