AIRPODS - EAR TIPS

I need to replace my Silicone Ear Tips (Small) on my newly purchased AirPod Pro. I am told this can only be done in store and not by post. This means I have to book an appointment to meet a technician (1 day off work), then they will order 2 ear tips, then I have to book with a technician again to collect (another day off work). These items are not held in stock. I have just purchased a new MacBook that took 2 days to arrive. I need replacement ear tips and I have to visit store twice for something so simple. Apple you have got this wrong - must be a better way of dealing with this. Already wasted 2 hours on the phone and chat. Neil.
