I get those all the time too. And another thing I've learned through the years is to not let them sell me an extended warranty on anything. The warranties cost more than the product most of the time. (smile)
Most cars these days have enough warranty to start with. By the time you drive out the warranty it's time to get another car.
And large items like computers, refrigerators have warranties that will cover for an extended period too.
Way I figure it if the item I have bought has a good warranty to begin with why waste my money on an extended warranty or for the Dog Patrol to come fix my computer.
They just try to get money out of ya no matter what the reason.
And then these computer places want to set up your computer for a pretty size-able sum. Gee Whiz I can do that myself. Have a friend who just recently purchased a new computer. The original cost was around $500 and by the time he let them install and get everything set up for him it was $1000.
