I use ebay Germany and no item in myibidder shows shipping costs.
Is it possible to add this feature?
Thanks.

Unfortunately, eBay does not always provides shipping reliable enough. Especially when shipping is calculated dynamically or seller offers multiple shipping methods.
Please always check eBay directly for the shipping cost based on your address.

OK, then I would like to have a comment field by an item where I could input the shipping costs. In this case I wouldn't have to call ebay every time I forgot the delivery price

There is "My Notes" field when you use Windows application.
The Web interface will have it added in the future.

I usually set the snipe amount when I add the item and know the shipping fees by that time.

Also, please note that seller may change the shipping if listing has no bids.

I checked Biet-o-matic which I have used before. It shows shippping costs, so it should be possible to read them...

If the seller changes them they could be reread during refresh (as the current bid for example).

But it is just my dream

I believe it shows German-based shipping cost only.
It's not reliable enough when I want to make it universal and available for users world-wide.

I'm still monitoring if any changes on eBay's side. If that will change for better, I will enable it again.
Just don't want users to to get wrong assumption on the shipping cost since it plays a good role in sniping.
