Have also had a look and they only offer a hat! You can however get t-shirts on some websites, just have a Google search.
Maybe something CCM should get into, it would be nice to have some branded gear to go with the bikes.
It’s a tough decision, if it was £700/£800 I would probably be keen but over £1000 just seems OTT. I understand the service is top notch but let’s be honest your local guy would do a service for £100 odd! I think one of the plus sides to going with CCM is that they will fix any warranty issues whilst carrying out the service so that would be a bonus. Let’s hope the maybe reduce the service pack slightly and offer a pay monthly plan!
