eBay whoops...

I undercharged on shipping once.I THOUGHT I had estimated more than enough,and when i shipped the package,I ended up losing nearly $30.00 over and above the cost of the item itself and my shipping quote.I shipped it anyway,but now I flat rate everything and after today,I realize I'm going to have to raise my shipping prices.In the past two weeks,prices are notably higher.If the item is beyond my knowledge of shipping,I take it down to the old UPS Store and get an estimate,then add a few dollars on top of that as a "just in case".
