You see this mentioned sometimes when people discuss C2W through Halfords but it's worth emphasising in light of some real life experience...
I bought a 2009 Specialized FSR XC via C2W from Halfords who got the bike from Leisure Lakes. I needed a replacment seat stay so I contacted my local Spesh dealer, Dales Cycles in Glasgow. I simply asked for a replacement seat stay for an 09 FSR XC. Nothing more than that. They got one from Specialized "free of charge".
Today I went into the shop to pick it up...
Sales Assistant: What's your postcode?
Me: blah blah
SA: Hmm...no record of you on our system. Where did you buy the bike?
Me: C2W from Halfords via Leisure Lakes
SA: Ah. In that case it's not free, it's £97
He then informs me that Specialized are not honouring any warranty claims on bikes bought via Halfords and he phones Specialized UK in front of me to confirm. At that point I was more annoyed by the fact that I was told it would be free, then the about turn. I never mentioned anything in my initial enquiry about where I got the bike from or that I expected it as a warranty, I just assumed it was the famous Specialized customer service. I managed to negotiate 25% off the price but it's still frustrating and I couldn't face the hassle of going back to Halfords who would then have to go to Leisure Lakes who would then have to go to Specialized.
The guy said Specialized would normally strip the dealer supplying Halfords of their ability to supply their bikes, but as Leisure Lakes are so big, they're getting away with it.
