Hi Aiden, [br]
[br]
We have the [https://www.ifixit.com/Store/Game-Console/Xbox-One-Motherboard-and-Paired-Optical-Drive/IF294-007|Xbox One Motherboard and Paired Optical Drive] in stock on our website. For various reasons, we remove inventory from Amazon listings when we we’re running low. [br]
[br]
And that Repair Business Toolkit listing on Amazon is a very old catalog page that some other seller has their inventory listed on. You can get the most current and most awesome version of the [https://www.ifixit.com/Store/Tools/Repair-Business-Toolkit/IF145-278|Repair Business Toolkit] on our website. [br]

In general, Amazon is a difficult marketplace to work with. They’re awesome for the customer but quite frustrating for the seller. We are in the process of adding more iPhone parts to Amazon—but you’ll always get the best price and best experience on ifixit.com when buying iFixit parts.
