>Amazon also seems to overstate these shipping dates to make Prime shipping look better. Almost every time I have ordered something via a 3rd party like that, it arrives before the earliest date Amazon says it could.

They do that for themselves as well. Their shipping estimates for super saver shipping is always exaggerated, with packages arriving in 2-3 business days rather than 5-7 estimate

Also worth noting, is new third parties are not allowed to give lower time estimates until they achieve a certain rating.
