It was conceived a few years back - but it never quite happened.

Groceries delivered to your home from internet orders was an intriguing idea, and for a while we thought we were close to getting it through Priceline and local retailers.

Now Walmart's going to give it a go.

Last time around, the delivery component never really came to fruition and the ordering ahead component apparently never made it to commercial viability, and it was scrapped.

It seems that e-orders work better on airfare and concert tickets than on chocolate milk and brussels sprouts, but the day when you can click your mouse and have groceries delivered to your door might finally be on its way.

Walmart is trying its "Walmart To Go" program in a test market in San Jose.
