We have used this service twice for the television we bought from Costco. We were immediately connected to a very able English speaking technician in the United States, a miracle, who quickly helped us with our problems. This is very fortunate since our television had to be replaced once.
I just ordered a laptop from Costco without much concern for comparison price. Knowing that Costco has a 90 day return policy (which they actually extended for us once), their concierge technical service, and the free extended warranty for electronic purchases makes me a loyal customer forever.
