1) Stock re-order levels and a stock re-order report
2) A new deal - Buy X or more of an item and change item price to £Y. This means you can offer discounts to an item's price if a customer buys in bulk.
3) I am going to look at revamping the customer orders features of E4E as at the moment they are a bit basic
As I work on E4E in my spare time and I am quite busy at the moment I don't anticipate any new release before the summer.
