Integrated mileage calculator for website

Can anyone recommend a mileage calculator that the customer inputs their collection and delivery postcodes?

I can but then I'd have to kill you

This is a basic one if it helps, and there are a few differences between this one and google as well as a couple of others.

So you don't know one then Rob? Come on mate you're last person i would have expected to offer no opinion

There are several, we have one on our website, as do several others, but they all come at a cost so you're probably better off just using google maps

Here is ONE example from codforum mileage calculator. Just change the rate to the one that applies to you, minimum charge if you have one and hey presto.

That's the same one that I use Rob, very easy to use.
