Buy.com uses AIT as one of their carriers for larger items such as TVs. AIT's tracking starus is poor, they are extremely slow -9 days from pick up to delivery California to Arizona and furthermore, they have poor handling, my TV showed up with a huge hole in the side of the box.
Buy.com took four days to determine how long it would take to replace or refund. That is absolutely ridiculous in today's business environment.
Buy.com was great in the past century, good in the last decade, and now should go quietly into .com history as one of the failure stories.
