I've just updated the manager page on lettuceshare.org to show product totals for a supplier. You might want to use this to compare the group's purchases against a packing slip or invoice from a supplier.
To view product totals, leave the username field empty on the manager page and pick a supplier and date that you're interested in. Make sure the "Group results" check box is checked and then click search. Results will show total quantity and price, and if there was only one purchase the username and the price they purchased at will be displayed. (Product price is not shown for grouped items because they can change per user.)
If a username is supplied during searching, the group results option will continue to function as before, which is to display the totals for that user.
