I completely agree. I emailed Amazon a while back because there was an add on item I really needed but could not buy. I understand they can't ship it free. That's fine, but like you said there was literally no way for me to purchase it and pay shipping. That's insane. They should make sure there's always a way for the customer to purchase something.

I also feel the SmartPost shipping is a broken promise. SmartPost almost always turns out to be 3 day shipping. 2 days from Amazon to the post office, then 1 day from post office to me.
