So I lost My left ear bud can I just buy the left one of is it possible to find

Hello there,

You can actually buy just the one missing AirPod if you wanted to. This link will break down prices depending on your AirPods model. From what I understand, you can contact support via https://apple.com/support or the Apple Support app, depending on your location, they should be able to ship you a replacement.

You can also visit a nearby Apple Service Provider for a replacement. Keep in mind you will probably need an appointment and/or the part may be ordered depending on inventory levels. This link should help you find something nearby: https://locate.apple.com/

Hope this helps!
