Interesting note on cpw's page about the warranty poll they did:
The results of our warranty poll! We received 27 responses covering all three Canon US repair centers.
USA Model Cameras bought from unauthorized dealers are eligible for warranty repair service. We had no reported incidents of USA-model purchases from unauthorized dealers being rejected for service.
Please note that this is just our data and observations, and the official policy of Canon Inc. may be subject to change, but for now we believe that USA model items are eligible for warranty service. We have changed the marking on these dealers as "Canon USA Warranty" in our listings.
I guess they're confirming that BigValueInc does get warranty service.
