I've used Safeway's home delivery service before. Wal-mart's as well. The whole, get your groceries delivered, it isn't such a great experience to be honest.

First of all, pretty much every single time, I was missing items!

Secondly, navigating the online store is a horrible experience. Finding things, thinking of what you need. The whole thing stinks.

The experience of walking down an isle and picking out what you need, is strangely more efficient.
