I recently loaded the snip plug-in to firefox and the web based interface is very nice, however something that I am use to seeing in other snipe programs is the shipping charges and a total bid price, is there any word on if these items are going to be added ?

Currently, I have this information in the system and it's being used by Windows software only.
Once columns will be customizable in the Web interface, you will have the ability to add "Shipping" column as well.

Unfortunately, I don't have exact ETA of this yet, but I hope to make it soon.
Meanwhile, "Shipping" information is added to the "Snipe" page.
