I found going to one widget for sales/purchases easier to track than fishing thru DM/PMs and having to remember if I missed someone in that mess.
Seems simple enough, and I am sure has internal tracking would help resolve issues should they arise.
Shows a list of sales/purchases in one spot as well as specific alerts at top for next step in the sale.
I can't see it now but generally: Confirm address / Confirm payment / confirm preparing / confirm shipped & closed. Boom.
Not sure why you had repeated alerts for the same thing.
My guess is that he clicked on 'save' multiple times thinking to sales alert flag would go away w/o dropping down to save the next step?
I did that allot at first trying to figure out why the action required alert did not go away or the auction did not close after I clicked on save for the 1st step.
