As far as I can judge, there are but still I believe you should check that info. The fact that Amazon specializes in returned, damaged in storage, used, or refurbished things means that inventory is continuously changing. As a result, Amazon cannot predict when an item will become available in the future. Keep checking back for updates, and submit your orders as soon as possible. Have a look at that trusted resource. Good luck
Everything at Amazon is a finely tuned, cost optimized process. Receiving is systematic, with well defined, secured, and audited systems for packages arriving at a loading dock. Only certified shippers will be permitted to enter, for the safety and security of the workers (and your own safety, really).
