$8000 in 4 years, with about $800 of that being shipping.
Edit: I'm confused... I almost always get the free super saver shipping, but this order report shows a shipping charge on every order I've had?
edit 2: NVM, I'm an idiot and didn't look two columns over where they show the promotion that removes the shipping.
Total shipping is about $400, not $800 once the free super saver is taken out.
