GW has a really good customer service record when it comes to missing spurs and bits.
Years ago a friend ordered the Green Tide from GW, one of their apoc bundles.
All 10 frames were missing the power claw.
Took it back to the local GW store where he purchased it and they submitted a claim.
All he was expecting was 10 power claws, but GW sent him 10 new frames!
This is where the craziness happens.
I think 7-8 of those frames were also missing the power claw.
He was opening them at the shop with the manager, so there was nothing shady going on.
They kept submitting a claim for the missing power claws, they kept sending full frames, and each round some of the frames were missing the power claw.
This pattern kept up until he finally received the 10th power claw.
But by that point he had over 400 boyz.
Not a bad deal for the cost of 100 boyz.
That is the most extreme case I know about.
But I tell it to show to what extent GW will go to ensure customer satisfaction.
