I think I see what you're getting at here and I agree 100%. Order History needs a "Quantity" column. They also need to pad their number output from the "Total" box correctly. I'm getting totals written out like $18.20725 and $169.5. It just looks rushed and amateurish, no offense.
You're aware, though, that you get a detailed order breakdown in your payment receipt from Paypal, right? Just checking.
