when entering inventory items at http://appninjas.com/account/ in the Product List, sometimes when you add a long product description it can change the page layout so that you can no longer see the "Delete" or the "Save" buttons.  If this happens, on most systems you can zoom the text on a page in or out by holding "Ctrl" and turning the scroll wheel on your mouse.  Doing so should reveal the missing buttons.
