Postage Cost calculator in Salesyard?

[MrEL]

Hi all
Im just wondering if this link would be worth while putting as a sticky in the salesyard section. If you put in the item dimensions , weight and sent from and destination postcodes it calculates what it will cost to mail it.
I thought it might make things a bit quicker and easier for sellers when people ask for a quote on the price including postage.
Here is the link

Thanks guys , hopefully it is of use to someone.
